“…MRI-guided biopsy is widely performed for tissue sampling of lesions with suspicious MRI characteristics which are not identified on second-look sonography [16, 18-20, 26-31]. The reported cancer detection rate for MRVAB ranges from 18% to 61% [19, 20], the majority of investigators reporting a probability of malignancy in the 20%–40% range [16, 17, 21, 27-29].…”

Purpose To correlate 9-gauge Magnetic Resonance imaging-guided Vacuum-Assisted breast Biopsy (MRVAB) with surgical histology to determine the upgrade rate and to correlate the frequency of MRVAB cancer diagnosis with breast MRI indications and enhancement characteristics of targeted lesions. Materials and Methods The HIPAA compliant study was approved by the institutional review board. A database search was performed of all MRVABs performed from January 1, 2005 to September 31, 2010. The breast MRI indications, history, age, risk factors, lesion size, enhancement characteristics, pathology at MRVAB and at surgery were documented. Fisher's exact test and Analysis of Variance were used for statistical analysis. Results A total of 218 lesions underwent MRVAB in 197 women (mean age 52 years, range 28 - 76 years), of which 85 (39%) had surgical correlation. (R1, #3) There were 48/218 (22%) malignant, 133/218 (61%) benign, and 37/218 (17%) high-risk lesions at MRVAB. Ten (12%) of 85 lesions were upgraded to malignancy at surgery, with a final malignancy rate of 25%. The frequency of malignancy was significantly higher in patients presenting for diagnostic (50/177, 28%) versus screening (4/41, 10%, P<0.05) evaluation, patients with ipsilateral cancer (22/49, 45%, P<0.001), lesions with washout kinetics (34/103, 33%, P < 0.05); and relatively higher in lesions with non-mass-like enhancement (26/76, 34%, P=0.07), which represented ductal carcinoma in situ in the majority (17/26, 65%, P<0.005). Conclusion Patients with ipsilateral cancer who have additional suspicious lesions identified on MRI require careful evaluation and biopsy to exclude additional sites of cancer that may impact surgical management.

“…In contrast, several studies have reported that MRI-guided core-needle biopsy and MRI-guided VAB may have a high diagnostic yield (96-99%) [17,18]. Tozaki et al [19] reported the need for MRI-guided VAB in Japan; however, this procedure is not yet accepted by insurance companies covering medical examination and treatment in Japan. Therefore, it is important to develop an infrastructure for MRI-guided biopsy in Japan.…”

“…Except for the recently published preliminary experience with MRI-guided vacuum-assisted breast biopsy (VABB) in Japan [13-15], there are no published data in Asian or Korean women. The aim of this prospective study was therefore to evaluate our initial clinical experience with MRI-guided VABB of breast lesions visible only on MRI in Korean women.…”

BackgroundMagnetic resonance imaging (MRI)-guided vacuum-assisted biopsy is the technique of choice for lesions that are visible only with breast MRI. The purpose of this study was to report our clinical experience with MRI-guided vacuum-assisted biopsy in Korean women.MethodsA total of 13 patients with 15 lesions for MRI-guided vacuum-assisted biopsy were prospectively entered into this study between September 2009 and November 2011. Biopsy samples were obtained in a 3-T magnet using a 9-guage MRI-compatible vacuum-assisted biopsy device. We evaluated clinical indications for biopsy, lesion characteristics on prebiopsy MRI, pathologic results, and postbiopsy complication status.ResultsThe clinical indications for MRI-guided vacuum-assisted biopsy were as follows: abnormalities in patients with interstitial mammoplasty on screening MRI (n = 10); preoperative evaluation of patients with a recently diagnosed cancer (n = 3); and suspicious recurrence on follow-up MRI after cancer surgery (n = 1) or chemotherapy (n = 1). All lesions have morphologic features suspicious or highly suggestive of malignancy by the American College of Radiology Breast Imaging Reporting and Data System category of MRI (C4a = 12, C4b = 2, C5 = 1). In two of the 15 lesions (13.3%, <6 mm), MRI-guided 9-gauge vacuum-assisted breast biopsy was deferred due to nonvisualization of the MRI findings that led to biopsy and the lesions were stable or disappeared on follow up so were considered benign. Of 13 biopsied lesions, pathology revealed four malignancies (4/13, 30.8%; mean size 15.5 mm) and nine benign lesions (9/13, 69.2%; size 14.2 mm). Immediate postprocedural hematoma (mean size 23.5 mm) was observed in eight out of 13 patients (61.5%) and was controlled conservatively.ConclusionsOur initial experience of MRI-guided vacuum-assisted biopsy showed a success rate of 86.7% and a cancer diagnosis rate of 30.8%, which was quite satisfactory. MRI-guided vacuum-assisted breast biopsy is a safe and effective tool for the workup of suspicious lesions seen on breast MRI alone without major complication. This biopsy may contribute to the early diagnosis of breast cancer in interstitial mammoplasty patients in Korea.
