The direction of tissue acquisition was chosen on the basis of the location of the introducer with respect to the lesion. Citation: American Journal of Roentgenology. The Journal Impact Quartile of American Journal of Roentgenology is Q1 . In published series of lesions that had MRI-guided needle localization and surgical biopsy, technical success rate was 98–100%; histologic analysis revealed cancer in 31–73% (of which up to half were DCIS) and high-risk lesions such as atypical ductal hyperplasia or LCIS in up to 29% [4, 9–18]. 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. The median size of these 27 lesions was 1.0 cm (range, 0.4–6.4 cm). 3A, 3B, 3C). The patient was then withdrawn from the magnet with her breast remaining in compression. After the examination, the unenhanced images were subtracted from the first contrast-enhanced images on a pixel-by-pixel basis. Frequency was in the anteroposterior direction. 2019;213: 234-237. 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. 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. For more than 100 years the AJR has been recognized as one of the best specialty journals in the world. A complication was encountered in one (4%) of 27 lesions and in one (5%) of 19 patients. 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]. A lesion was considered to be cancer if cancer was found at vacuum-assisted biopsy, surgical excision, or both. This case, therefore, may reflect a false-negative on the part of the MRI study rather than the biopsy procedure. American journal of roentgenology. Faktor dampak atau faktor pengaruh atau faktor dampak jurnal dari suatu jurnal akademik adalah ukuran yang mencerminkan jumlah rata-rata sitiran (sitasi) tahunan untuk artikel terbaru yang dipublikasikan … Biopsy of MRI-detected lesions can also be performed percutaneously. One complication was encountered, a hematoma that resolved with compression. When the biopsy device was fully inserted into the white introducer, the center of the mouth was positioned where the tip of the obturator had been. While the postexamination images were being acquired, the technologist retrieved the samples from the collecting chamber and placed them in formalin. 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. Visit the AJR Coronavirus Disease (COVID-19) Collection to view all AJR articles on COVID-19.. 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. The goal of the ARRS is maintained through an annual scientific and educational meeting and through publication of the American Journal of Roentgenology, … However, “second-look” sonography fails to identify a sonographic correlate in up to 77% of MRI-detected lesions referred for biopsy [5–7]. Further work characterizing MRI patterns of specific benign and malignant lesions is necessary. An ultrafast sequence provides early enhancement of lesion characteristics that optimize the characterization of the fast protocol, increasing positive predictive values without increasing time. 5A, 5B, 5C): the reported sensitivity of MRI for DCIS has ranged from 40% to 100% [37]. 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. Scientific Journal Selector (2018-2019), we collect latest information of SCI journals, include ISSN, h-index, CiteScore, online submission URL, research … 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). 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. Editorial. Our imaging protocol includes a localizing sequence followed by a sagittal fat-suppressed T2-weighted sequence (TR/TE, 4,000/85). In the remaining six women, directed sonography was not performed at the discretion of the interpreting radiologist and treating clinician. The median histologic size of infiltrating carcinoma was 0.8 cm (range, 0.2–1.5 cm). 115(12):1989-1997, December 2020. The current editor-in-chief is Thomas H. Berquist. The complication was a clinical hematoma, evident as swelling with bluish discoloration immediately after biopsy. Vacuum-assisted biopsy is faster, less invasive, and less expensive than surgery, and it causes no deformity [32]. 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]. In one (4%) of the 27 lesions, a 5.0-cm non–mass lesion sampled at vacuum-assisted biopsy, vacuum-assisted biopsy histology revealed markedly atypical ductal hyperplasia and lobular carcinoma in situ (LCIS); surgical excision showed markedly atypical ductal hyperplasia focally reaching the level of low-grade cribriform DCIS, arising in a background of florid mammary sclerosing adenosis and columnar cell changes, as well as extensive LCIS (Fig. 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. The obturator was not placed inside the patient at this point, but rather measured to determine where to set the depth stop (Fig. 5A, 5B, 5C). 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. Listen to the latest podcasts by selecting one of the following: This index can be widely applied to the productivity and impact of a scholarly journal, individual researcher or a group of scientists, such as a department or university or country. This procedure helped to ensure that the biopsy device entered through the incision site, even when that site was later obscured by the needle guide. Section Editor's Notebook: Women's Imaging—Problem Solving in Everyday Practice. 1F). Cancer was found at vacuum-assisted biopsy in six (22%) of 27 lesions. The society has been a forum for progress in radiology since shortly after the discovery of the X ray and is dedicated to the goal of the advancement of medicine through the science of radiology and its allied sciences. For more than 100 years the AJR has been recognized as one of the best specialty journals in the world. The initial attempt at clip placement was successful in 20 (77%) of 26 lesions, and a second attempt was successful in five (19%) of 26 lesions; in one lesion (4%), clip placement failed in spite of two attempts. Although it remains controversial, excision may also be warranted for lesions yielding LCIS at percutaneous biopsy [35]. 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. 1976. One false-negative case occurred in a woman with Paget's disease. We thank the 20 women who enrolled in the study for making this work possible. The tray with the stylet was removed from the room before MRI was performed. Country of Publication. MRI-guided vacuum-assisted biopsy, pioneered by Sylvia Heywang-Kobrunner, has advantages compared with other biopsy methods for the diagnosis of MRI-detected lesions [25]. 10.2214/AJR.18.21007 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. The monthly American Journal of Roentgenology is a highly respected peer-reviewed journal with a worldwide circulation of close to 25,000. Abstract. Compared with fine-needle aspiration biopsy, vacuum-assisted biopsy has a higher technical success rate and fewer inadequate specimens [11, 15, 19–21]. 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. 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). Perhaps use of a clip with more artifact or using different pulse sequences would help to assess clip location on MRI. Laura Liberman 1, Elizabeth A. Morris 1, D. David Dershaw 1, Cynthia M. Thornton 1, Kimberly J. Postbiopsy collections of air (n = 5), fluid (n = 5), or both (n = 16) measuring a median of 1.9 cm (range, 0.6–3.2 cm) were observed on MRI in all lesions. 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). Clip placement was attempted in 26 lesions and was successful in 25 (96%) of 26. 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. Update on Breast Density, Risk Estimation, and Supplemental Screening, Review. Publication Frequency. Deep anesthesia was provided by injecting 10–20 mL of 1% lidocaine hydrochloride (Xylocaine [10 mg/mL], AstraZeneca) with epinephrine 1:100,000. The study shows that fastMRI can generate “diagnostically interchangeable” MRI images of knee injuries while using about 75 percent less raw data from the … CONCLUSION. 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]. The median size of the MRI lesions in these eight cancers was 1.1 cm (range, 0.6–6.5 cm). Vacuum-assisted biopsy and surgical histology are correlated in Table 1. Placement of a localizing clip, attempted in 26 lesions, was successful in 25 (96%) of 26, and the clip was retrieved on specimen radiography in 22 (96%) of 23.

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]. 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. A clip can enable subsequent localization under the guidance of mammography (or sonography, if it is sonographically evident). In all instances of unsuccessful clip deployment, the collagen pledget was visible in the mouth of the biopsy handpiece after its removal; therefore, failure of clip deployment was immediately apparent to the radiologist performing the biopsy. Four of eight cancers were identified in women undergoing MRI for the assessment of disease extent (multifocal cancer in the ipsilateral breast in two, multicentric cancer in the ipsilateral breast in one, and contralateral cancer in one), and four were detected in women who are at high-risk for breast cancer undergoing MRI for screening. About AJR. 2019;213:485-489. A false-negative finding was defined as a lesion yielding benign results without atypia at vacuum-assisted biopsy and cancer at surgery. If the obturator was superficial in relation to the lesion, the obturator was removed, leaving the introducer in place. In five of these six cancers, surgical excision confirmed the diagnosis of cancer. A vitamin E marker was placed over the expected lesion site (Fig. MRI-Guided Breast Biopsy: Influence of Choice of Vacuum Biopsy System on the Mode of Biopsy of MRI-Only Suspicious Breast Lesions, Technical Innovation. Seventeen were mass lesions and 10 were non–mass lesions. Get Content & Permissions Free. 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. Vacuum-assisted biopsy and surgical histology were correlated. One complication occurred: a hematoma that resolved with compression. The results, published in the American Journal of Roentgenology, found no significant differences in the radiologists' evaluations. The American Journal of Roentgenology (AJR) is a monthly peer-reviewed journal that covers topics in radiology. Compared with automated core biopsy, vacuum-assisted biopsy retrieves a large volume of tissue, which can help compensate for decreasing lesion conspicuity during MRI-guided biopsy, and provides better characterization of lesions containing atypical ductal hyperplasia and DCIS [32]. Total imaging time per breast, including three contrast-enhanced acquisitions, was approximately 20 min. Targeting images.—The patient was positioned prone with both breasts in a dedicated surface breast coil (Open Breast Array Coil, model OBC, MRI Devices, Waukesha, WI). 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]. 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. We found that the clip produced such little artifact on MRI that it was sometimes difficult to distinguish from low-signal foci of air introduced during the biopsy. In four (17%) of 24 lesions the radiologist noted that differentiating the clip from low-signal foci representing air was difficult, but could be accomplished by comparing images before and after clip placement. American Journal of Roentgenology is a peer-reviewed scientific journal. 2005;184:1782-1787. The front end of the probe was placed back into the introducer. 2020;214: 282-295. 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. Since less data is required, MRI scans could run nearly 4x faster. 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.
