After tissue acquisition was complete, the biopsy device was removed, the obturator was reinserted, and sagittal T1-weighted images (3-mm slice thickness), the postexamination images, were obtained to assess the completeness of tissue acquisition. American Journal of Roentgenology is a peer-reviewed scientific journal. Citation: American Journal of Roentgenology. Vacuum-assisted biopsy and surgical histology were correlated. The direction of tissue acquisition was determined by the radiologist performing the biopsy by turning the arrow on the biopsy probe in the desired direction. 2020;214: 282-295. MRI scans are excellent tools for doctors, allowing a … The 9-gauge biopsy device used in this study is larger than the 11-gauge systems most commonly used for stereotactic biopsy. For the two lesions that were posterior to the grid, the skin incisions were made as close to the lesions as possible, posteriorly within the grid, and suction was applied in the posterior direction to acquire tissue. 1A) by one of three attending radiologists specializing in breast imaging. Data were entered into a computerized spreadsheet (Excel, Microsoft, Redmond, WA) for analysis. OBJECTIVE. The patient was then withdrawn from the magnet with her breast remaining in compression. The stylet was advanced to the depth stop (Fig. The front end of the probe was placed back into the introducer. The biopsy was technically successful in 19 (95%) of 20 women. However, the clip can be readily identified on mammography. SDC. Previous studies have reported technical success rates of 61–100% for MRI-guided fine-needle aspiration [11, 15, 19–21], 33–100% for MRI-guided automated core biopsy [12, 15, 22–24], and 93–98% for MRI-guided vacuum-assisted biopsy [25, 28]. Favorites; PDF. Compared with historical Journal Impact data, the Metric 2019 of American Journal of Roentgenology dropped by 3.92% . The radiologist performing the biopsy reviewed MRIs obtained during and after biopsy to determine the presence and extent of postbiopsy changes (e.g., hematoma or air); to assess whether the MRI target was sampled or possibly excised; and to evaluate whether the localizing clip was visible, noting any problems with visualization of the clip. In one woman, the biopsy device could not be inserted because of hold-up of the white plastic introducer at the skin surface; the vacuum-assisted biopsy was aborted, and the lesion underwent needle localization and surgical excision. 5A, 5B, 5C). This case, therefore, may reflect a false-negative on the part of the MRI study rather than the biopsy procedure. 10.2214/ajr.184.6.01841782. Images were obtained sagittally, for an acquisition time per volumetric acquisition of less than 3 min each. Like many of the more long-lived academic publications, there have been a number of name changes over the years (see below). Informed consent, preparation before the biopsy, biopsy equipment, and radiologists.—Informed consent was obtained for all biopsy and needle localization procedures. In spite of these challenges, investigators have reported clinical experience with MRI-guided needle localization for surgical excision [4, 9–18] and MRI-guided percutaneous biopsy using a fine needle [11, 15, 19–21], automated core needle [12, 15, 22–24], or vacuum-assisted biopsy probe [25–29]. The vacuum-assisted biopsy device used in our study allows rapid acquisition of multiple specimens, deferring specimen collection until after tissue acquisition is complete. Publication End Year. The time of the biopsy, in minutes, was determined by calculating the interval between the beginning of the MRI localizing sequence and the end of the final MRI sequence performed after clip deployment. The results, published in the American Journal of Roentgenology, found no significant differences in the radiologists' evaluations. Placing the clip.—The localizing clip (MammoMark Biopsy Site Marker, Artemis Medical, Hayward, CA) was a titanium clip attached to a resorbable collagen pledget. Those results represent the culmination of nearly two years of open research by FAIR and NYU Langone Health, which is a group of academic medical centers in New York City. Country of Publication. Among these 27 lesions, quadrant location was upper outer quadrant in 11, lower outer quadrant in 11, upper inner quadrant in four, and lower inner quadrant in one. Listen to the latest podcasts by selecting one of the following: The sixth cancer was a 0.7-cm mass in which the imaging target may have been excised at MRI-guided vacuum-assisted biopsy, and histologic analysis of vacuum-assisted biopsy specimens yielded infiltrating lobular carcinoma; the surgical specimen showed fibrosis and changes related to prior biopsy, with no residual carcinoma (Fig. The median histologic size of infiltrating carcinoma was 0.8 cm (range, 0.2–1.5 cm). Performing the biopsy, obtaining postexamination images, and collecting the specimens.—After appropriate positioning was confirmed on MRI, the obturator was removed and the biopsy device was inserted (Fig. The utility of breast MRI is dependent on the availability of methods to perform biopsy of lesions detected on MRI only. A twisting motion was helpful when advancing the stylet. Biopsies were performed with a commercially available 9-gauge vacuum-assisted MRI-compatible biopsy system (ATEC Breast Biopsy System, Suros Surgical Systems, Indianapolis, IN) (Fig. It is published by the American Roentgen Ray Society (ARRS) and is based in Leesburg, VA. A lesion was considered to be cancer if cancer was found at vacuum-assisted biopsy, surgical excision, or both. We found that if the lesion was close to but posterior to the grid, we could position the probe adjacent to the lesion and use the suction to acquire tissue in the posterior direction, enabling us to obtain diagnostic material. Surgical excision of the site that had vacuum-assisted biopsy showed a few scattered foci of DCIS with high nuclear grade at the anterior margin of resection (Fig. False-negative results are a potential problem during any biopsy: reported false-negative rates are 0–8% for stereotactic 14-gauge automated core biopsy, 3% for stereotactic 11-gauge vacuum-assisted biopsy, and 0–8% for needle localization and surgical biopsy [38, 39]. The obturator was not placed inside the patient at this point, but rather measured to determine where to set the depth stop (Fig. Imaging-Based Approach to Axillary Lymph Node Staging and Sentinel Lymph Node Biopsy in Patients With Breast Cancer, Review. Although no anxiolytic medication was administered IV, patients were pretreated as needed with oral benzodiazepines such as diazepam (Valium [one or two 5-mg doses], Roche Pharmaceuticals, Manatí, PR) or lorazepam (Ativan [one or two 0.5-mg doses], Wyeth-Ayerst Laboratories, Philadelphia, PA) on the morning of the procedure, as discussed with the referring clinician. A paper written by the team describing the new technology is to be published in the American Journal of Roentgenology. MRI-Guided Vacuum-Assisted Breast Biopsy Performed at 3 T With a 9-Gauge Needle: Preliminary Experience, Accuracy of MRI in the Detection of Residual Breast Cancer After Neoadjuvant Chemotherapy, Fast MRI-Guided Vacuum-Assisted Breast Biopsy: Initial Experience. Our goal was to use DL to accelerate MRI … The indication for breast MRI in these 20 women was assessment of disease extent in women with known cancer diagnosed within 6 months of breast MRI in 10 and screening of women who are at high-risk for breast cancer in 10. American Journal of Roentgenology IF is decreased by a factor of 0.13 and approximate percentage change is -3.92% when compared to preceding year 2017, which shows a falling trend. MRI-guided vacuum-assisted biopsy is a fast, safe, and accurate alternative to surgical biopsy for breast lesions detected on MRI. Get Content & Permissions Free. Articles in this collection are free and open access. A skin nick was made with a scalpel. The four screening-detected cancers were in two women: one woman with bilateral breast cancer and one woman with multifocal invasive breast cancer. Further work is needed to optimize clip conspicuity on MRI and methods of clip deployment. Tissue was acquired by stepping on the foot pedal. The tray with the stylet was removed from the room before MRI was performed. The average time to perform biopsy of a single lesion was 35 min in our study. 1E). The monthly American Journal of Roentgenology is a highly respected peer-reviewed journal with a worldwide circulation of close to 25,000. The diagnosis of atypical ductal hyperplasia at percutaneous biopsy is an indication for surgical excision [32]. Total imaging time per breast, including three contrast-enhanced acquisitions, was approximately 20 min. Vacuum-assisted biopsy and surgical histology are correlated in Table 1. In the latter three lesions, the distances from the clip to the wire were 3.4, 4.0, and 4.1 cm, respectively; all three clips were deep (medial) in relation to the localizing wires. In our initial experience with a new method, the technical success rate of MRI-guided vacuum-assisted biopsy was 95%. In women at high risk of developing breast cancer, MRI detects a cancer occult to mammography and physical examination in 2–8% [1]. For MRI-detected lesions warranting biopsy that had neither mammographic nor sonographic correlates, MRI-guided localization and surgical excision were performed [17]. At our institution, diagnostic breast MRI examinations were performed with the patient prone in a 1.5-T commercially available system (Signa, General Electric Medical Systems, Milwaukee, WI) using a dedicated surface breast coil. Dibandingkan dengan Faktor Dampak historis, Faktor Dampak 2019 dari American Journal of Roentgenology turun 3.92 %. The study focused specifically on knee scans, and we are now working to extend the results to other parts of the body. Predictors for Failing the American Board of Radiology Core Examination Gary Lloyd Horn , Stephen Herrmann , Irfan Masood , Clark R. Andersen , Quan Dang Nguyen American Journal of Roentgenology . The vacuum-assisted biopsy device is helpful for biopsy of posterior lesions. 1G). A sagittal T1-weighted MRI study (3-mm slice thickness) was then performed to document the location of the obturator, with the ideal location of the tip of the obturator being at the site of the lesion. Address correspondence to L. Liberman ([email protected]). 1B). Biopsy of suspicious MRI-detected lesions is necessary for definitive diagnosis. 3A, 3B, 3C). One woman declined placement of a clip. Although the frequency of cancer is higher among MRI-detected lesions that have sonographic correlates as compared with those that do not (43% vs 14%, p = 0.01), suspicious MRI-detected lesions that lack sonographic correlates also warrant biopsy [7]. The horizontal (x-axis) and vertical (y-axis) coordinates of the lesion were determined on the basis of the spatial relationship between the lesion, vitamin E marker, and grid lines. Section thickness was between 2 and 3 mm without a gap using a matrix of 256 × 192 and a field of view of 18–22 cm. NYU Langone Health and Facebook teamed up to launch the fastMRI initiative two years ago in a bid to speed up MRI scans. In our practice, breast MRI examinations were interpreted by breast imaging specialists in conjunction with clinical history and other breast imaging studies, including mammograms and sonograms when available, using previously described criteria [31]. Obtaining a two-view mammogram after biopsy is essential to assess location of the clip with respect to the biopsy cavity. Two lesions were posterior to the biopsy compression grid. The median number of specimens obtained per lesion was eight (range, 6–14). Before participating in this study, these three radiologists had performed an average of 99 MRI-guided needle localization procedures (range, 89–119) and an average of 335 stereotactic 11-gauge vacuum-assisted breast biopsies (range, 311–364). The radiologist also reviewed the specimen radiograph to determine whether the clip was retrieved at surgery. Our anecdotal impression is that turning the biopsy device so that it faces downward (6-o'clock position) during clip deployment, removing the clip's introducer after clip deployment, and then removing and inspecting the biopsy handpiece to ensure that the clip deployed were helpful. The obturator was identified on MRI as a low-signal focus measuring a median of 0.3 cm (range, 0.2–0.6 cm) in width. The results, published in the American Journal of Roentgenology, found no significant differences in the radiologists' evaluations. The results, published in the American Journal of Roentgenology, found no significant differences in … A woman was invited to participate in the study if she was scheduled for MRI-guided needle localization of a nonpalpable mammographically occult lesion, if she had undergone diagnostic breast MRI at our institution for screening of women who are at high risk for breast cancer or for extent of disease assessment, if logistics (staffing, magnet time, and operating room schedules) allowed the biopsy to be performed on the day of her surgery, and if her surgeon approved her participation. Frequency and Cancer Yield of BI-RADS Category 3 Lesions Detected at High-Risk Screening Breast MRI, Review. After the examination, the unenhanced images were subtracted from the first contrast-enhanced images on a pixel-by-pixel basis. In 23 lesions, only a single round of tissue acquisition was necessary; in four lesions, MRI after the first round of tissue acquisition did not ensure lesion sampling, and a second round of tissue acquisition was performed. Copyright © 2013-2020, American Roentgen Ray Society, ARRS, All Rights Reserved. The current editor-in-chief is Thomas H. Berquist. The protocol called for a two-view mammogram after localization to document the location of the localizing wire and clip, which was sent with the patient for use during surgery, and for specimen radiography to confirm retrieval of the clip. 1C). The depth of the lesion from the skin surface in millimeters (z) was calculated by determining the number of sagittal slices between the skin and the lesion and multiplying by 3 (to account for the 3-mm slice thickness). MRI review suggests that the MRI target may have been excised and that the microscopic DCIS in the surgical specimen was occult at MRI (Fig. Seventeen were mass lesions and 10 were non–mass lesions. In five of these six cancers, surgical excision confirmed the diagnosis of cancer. The stylet was placed inside the introducer, advanced to the appropriate depth, and then removed, with the introducer remaining in position. Alternatively, if the obturator was deep in relation to the lesion, the obturator and introducer were simply pulled back to the appropriate depth. If the obturator was superficial in relation to the lesion, the obturator was removed, leaving the introducer in place. Breast MRI can detect cancer that is mammographically and clinically occult. Deep learning (DL) image reconstruction has the potential to disrupt the current state of MRI by significantly decreasing the time required for MRI examinations. In more than two thirds of the lesions (70%), both vacuum-assisted biopsy and surgery yielded benign results. The current editor-in-chief (August 2020) is Andrew B. Rosenkrantz. The clear obturator was then removed from the white introducer, and the sharp stylet was placed inside the white introducer as far as it could go (Fig. 1D). Screening Guidelines Update for Average-Risk and High-Risk Women. Vacuum-assisted biopsy was successfully performed in 19 (95%) of the 20 women. Cancer was found at vacuum-assisted biopsy in six (22%) of 27 lesions. Read papers from AJR. Cancer was found in eight (30%) of 27 lesions and in six (32%) of 19 women, based on review of vacuum-assisted biopsy and surgical histology. However, “second-look” sonography fails to identify a sonographic correlate in up to 77% of MRI-detected lesions referred for biopsy [5–7]. MRI review suggested that the MRI target may have been excised at vacuum-assisted biopsy in three of these cancers (two DCIS and one infiltrating lobular carcinoma) and was sampled at vacuum-assisted biopsy in five. Imaging–histologic correlation, essential after breast biopsy using any guidance method [34], is particularly important after MRI-guided biopsy because of the limitations of other methods to confirm lesion retrieval. A complication was encountered in one (4%) of 27 lesions and in one (5%) of 19 patients. Preparing the probe.—The clear obturator was placed inside the white introducer, and the depth stop was set so that it was the appropriate distance from the tip of the clear obturator. MRI-guided needle localization.—After MRI-guided vacuum-assisted biopsy and clip placement had been completed, MRI-guided needle localization was performed using previously described methods [17] with an MRI-compatible hookwire (MReye Modified Kopans Spring Hook Localization Needle [20-gauge], Cook, Bloomington, IN). Cancers diagnosed included multicentric, multifocal, or contralateral disease in women with proven cancer and cancers found at MRI screening of women at high risk for breast cancer. For MRI-detected lesions warranting biopsy, correlative sonography was performed at the discretion of the radiologist interpreting the MRI study; if a sonographic correlate was identified, biopsy or localization was usually performed under sonographic guidance. Previous studies have shown that the likelihood of undergoing a single therapeutic operation is significantly higher in women with cancers diagnosed by percutaneous biopsy rather than surgical biopsy [32]. Further work with more women is necessary, including optimization of equipment and techniques for biopsy and clip placement, potential use of long-acting contrast agents, imaging–histologic correlation, and long-term follow-up, so that we can offer women the benefits of MRI in detecting breast cancer while minimizing surgeries for lesions that are benign. A faster biopsy also enables increased throughput in the magnet and is more comfortable for the patient. We injected a generous wheal of anesthetic to increase breast thickness. Immobilizing the breast without excessive compression may be helpful during MRI-guided biopsy to maximize breast thickness, avoid interfering with lesion enhancement [28], and minimize the “accordion effect” described with clip placement [33]. The depth of the skin surface from the outer aspect of the needle guide was 20 mm (because the needle guide was 2-cm thick). This study was performed to evaluate a new method for performing MRI-guided vacuum-assisted breast biopsy in a study of lesions that had subsequent surgical excision. MRI-guided vacuum-assisted breast biopsy, which has been successfully performed in more than 500 lesions in Europe [29], was recently approved for use in the United States. Specimen radiography showed retrieval of the localizing wire, but the clip was not identified. An axial localizing T1-weighted sequence was performed, and the volume of interest was selected to include the compression device and a vitamin E marker placed over the expected lesion site. In approximately one quarter of lesions (23%), cancer was found at MRI-guided vacuum-assisted biopsy. American Journal of Roentgenology, AJR The official journal of the American Roentgen Ray Society. Fast MRI-Guided Vacuum-Assisted Breast Biopsy: Initial Experience. The results, published in the American Journal of Roentgenology, found no significant differences in the radiologists' evaluations. fastMRI: An open dataset and benchmarks for accelerated MRI arXiv Code Website Accelerating Magnetic Resonance Imaging (MRI) by taking fewer measurements has the potential to reduce medical costs, minimize stress to patients and make MRI possible in applications where it is currently prohibitively slow or expensive. The breast undergoing localization was placed in a dedicated biopsy compression device using a commercially available grid-localizing system (Biopsy Positioning Device, model MR-BI-160, MRI Devices) or a slightly modified design of the commercially available model. The clip was evident as a low-signal focus measuring a median of 0.6 mm (range, 0.4–0.6 mm). The purpose of this study was to evaluate a new method for performing MRI-guided vacuum-assisted breast biopsy in a study of lesions that had subsequent surgical excision. Surgical histologic analysis showed fibroadenoma, other benign findings, and biopsy site changes. In preparation for clip placement, the blue tubing was peeled off the biopsy handpiece, and the front end of the probe (the portion with the mouth) was separated from the hand-piece portion. In two of these three lesions, MRI review indicated that the clip had deployed deep in relation to the biopsy site; in the third, the clip was at the biopsy site, but the wire had migrated superficially, perhaps because it was not firmly anchored in the biopsy cavity. The study shows that fastMRI can generate “diagnostically interchangeable” MRI images of knee injuries while using about 75 percent less raw data from the … 2019;213: 234-237. Opinion. If you use the fastMRI data or this code in your research, please consider citingthe fastMRI dataset paper: There were discussions about officially renaming AJR as the American Journal of Radiology in the mid-1970s but it was decided that the original name had importan… Underestimates have been encountered with every existing percutaneous biopsy method. The latest h-index of American Journal of Roentgenology is 182.The h-index is defined as the maximum value of h such that the given author/journal has published h papers that have each been cited at least h times. After the biopsy device was placed, the time of each round of tissue acquisition was determined, in seconds, by calculating the interval between stepping on the foot pedal to begin to acquire tissue and releasing the foot pedal at the completion of tissue acquisition, including any interval injection of anesthesia. Recognized as an undisputed leader in the field for over 100 years, the AJR is for radiologists who need clinically useful information; cutting-edge research; and educational and SAM/CME articles. The control module was outside the MRI scanner; only the foot pedal and biopsy device came into the room with the magnet. The stylet was placed in the incision until the white plastic introducer entered the skin (to create the tract) and was then removed. I. Thomassin-Naggara has provided remunerated lectures for GE Healthcare, Guerbet, Hologic, Canon, and Samsung and serves on advisory boards for Siemens Healthineers and Bard. Image acquisition started after injection of contrast material and saline bolus. The mammogram obtained after biopsy confirmed a 3-cm soft-tissue mass with air, consistent with the clinically evident hematoma. ... Official journal of the American Roentgen Ray Society, 1976- and the American Radium Society, 1976-1980. online access Musculoskeletal radiologists reviewed two sets of knee MRIs from 108 patients, one set using the standard imaging techniques, and one set using the fastMRI AI model. Frequency was in the anteroposterior direction. American journal of roentgenology. Although it remains controversial, excision may also be warranted for lesions yielding LCIS at percutaneous biopsy [35]. The clip was then placed inside the probe as far as it would go (Fig. For example, if the lesion was 30 mm deep in relation to the skin, the desired distance from the tip of the obturator to the depth stop was 50 mm (30 + 20 = 50 mm). Since less data is required, MRI scans could run nearly 4x faster. Copyright © 2013-2020, American Roentgen Ray Society, ARRS, All Rights Reserved. The hematoma resolved with compression and did not delay subsequent surgery. A sagittal T1-weighted MRI study (3-mm slice thickness) was then performed. A vitamin E marker was placed over the expected lesion site (Fig. American Journal of Roentgenology with Read by QxMD. Thin breasts pose challenges for MRI-guided vacuum-assisted biopsy, as for stereotactic biopsy [40]. For MRI-detected lesions that can be seen on sonography, biopsy can be performed under sonographic guidance. In the interchangeability study, which was published in the American Journal of Roentgenology, radiologists reviewed both traditional MRIs and images generated with an AI model from about 75 percent less raw data. MRI sequences performed after completion of tissue acquisition were reviewed for 26 lesions; in one lesion these images were not available because of magnet malfunction. 10.2214/AJR.18.21007 OBJECTIVE. Single lesions in 11 women underwent biopsy and two lesions in eight women underwent biopsy. The Journal Impact 2019-2020 of American Journal of Roentgenology is 3.190, which is just updated in 2020. Founded in 1907, the monthly American Journal of Roentgenology (AJR) is the world’s longest continuously published general radiology journal.AJR is recognized as among the specialty’s leading peer-reviewed journals and has a worldwide circulation of close to 25,000. Editorial. Twenty women scheduled for MRI-guided needle localization and surgical biopsy were prospectively entered in the study. For more than 100 years the AJR has been recognized as one of the best specialty journals in the world. The sensitivity of MRI is high, reported as 94–100%, but it has lower specificity, ranging from 37% to 97% [4]. The median size of 27 MRI-detected lesions that had biopsy was 1.0 cm (range, 0.4–6.4 cm). A second lesion became increasingly hyperintense on delayed images and underwent MRI-guided needle localization without biopsy during the same procedure, yielding another fibroadenoma and stromal fibrosis at surgery. Other maneuvers described for stereotactic biopsy that may be useful for MRI-guided biopsy of thin breasts include extrinsic circumferential pressure on the breast and use of a reverse-compression paddle; with the latter method, when the probe is placed deep into the breast, it displaces the skin and subcutaneous tissues into the aperture on the side opposite the skin entry site without piercing the skin [40]. The complication was a clinical hematoma, evident as swelling with bluish discoloration immediately after biopsy. The protocol for this study was approved by our institutional review board. Citation: American Journal of Roentgenology. The ability to position the vacuum-assisted biopsy device adjacent to the lesion and still acquire tissue from the lesion is another advantage of vacuum-assisted biopsy over automated core biopsy [32]. The distance from the clip to the localizing wire was 1 cm or less in 19 (76%) of 25 lesions, 1.1 cm in three lesions (12%), and greater than 3 cm in three lesions (12%). Twenty-seven lesions underwent biopsy in 19 women having a median age of 51 years (range, 19–64 years). We encountered some difficulties with clip deployment, with a second attempt necessary in almost one quarter of the cases. The Journal Impact Quartile of American Journal of Roentgenology is Q1 . The median size of these 27 lesions was 1.0 cm (range, 0.4–6.4 cm). Resistance was felt when the clip touched the end of the “mouth,” indicating that it had reached the appropriate depth. The stylet was then placed through the needle guide in the appropriate orientation with the tip protruding only slightly from the far side of the needle guide, and the tip of the stylet was placed in the skin at the site of the scalpel incision before attaching the needle guide to the grid. The median time to perform MRI-guided vacuum-assisted biopsy, from the original axial localizing images to the final images obtained after clip deployment, was 35 min (mean, 35 min; range, 24–48 min) for a single lesion and 65 min (mean, 69 min; range, 62–86 min) for two lesions. In one (4%) of the 27 lesions, a 0.4-cm smooth mass in a woman with Paget's disease of the nipple, MRI-guided vacuum-assisted biopsy yielded fibroadenoma and stromal fibrosis; MRI after vacuum-assisted biopsy showed that the MRI target may have been excised. Some posterior lesions cannot be captured within the biopsy grid, a problem that can also be encountered when performing stereotactic biopsy with the patient in the prone position [40]. Vacuum-assisted biopsy also facilitates placement of a clip that can be used for subsequent needle localization [33]. In this series, authors of select AJR articles discuss how their studies were performed, the results, and how the studies changed their practices. The clip introducer was turned 180° and removed, the biopsy handpiece was removed and inspected to make sure that the clip had not been retained in the mouth, and the introducer was removed. MRI-Guided Breast Biopsy: Influence of Choice of Vacuum Biopsy System on the Mode of Biopsy of MRI-Only Suspicious Breast Lesions, Technical Innovation. One woman at high risk for breast cancer who was 19 years old did not have a mammogram; in the remaining 19 women, mammographic parenchymal density [30] was class 4 (dense) in one, class 3 (heterogeneously dense) in 14, and class 2 (scattered fibroglandular densities) in four. 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2I), including one lesion that yielded benign findings at vacuum-assisted biopsy and a microscopic focus of atypical ductal hyperplasia at surgery.
