The purpose of this multicenter study was to determine the accuracy and clinical value of a dedicated breast biopsy system which allows for MR-guided vacuum biopsy (VB) of contrast-enhancing lesions. In five European centers, MR-guided 11-gauge VB was performed on 341 lesions. In 7 cases VB was unsuccessful. This was immediately realized on postinterventional images or direct follow-up combined with histopathology-imaging correlation; thus, a false-negative diagnosis was avoided. Histology of 334 successful biopsies yielded 84 (25%) malignancies, 17 (5%) atypical ductal hyperplasias, and 233 (70%) benign entities. Verification of malignant or borderline lesions included reexcision of the biopsy cavity. Benign histologic biopsy results were verified by retrospective correlation with the pre- and postinterventional MRI and by subsequent follow-up. Our results indicate that MR-guided VB, in combination with the dedicated biopsy coil, offers the possibility to accurately diagnose even very small lesions that can only be visualized or localized by MRI.

“…Because of the limited specificity of MRI, minimal invasive biopsy is required for MR-only visible suspicious lesions that cannot be identified with mammography or ultrasonography (US). Therefore, MR-guided biopsy is widely performed in the United States [1][2][3] and Europe [4][5][6][7][8][9][10] to avoid unnecessary surgical biopsy.…”

MR-guided vacuum-assisted breast biopsy: is it an essential technique?

et al. 2008

“…The flat plates compress the breast so that it maximally occupies the most sensitive region of the coil to maximize coil filling factor, allow prescription of a thin 3D volume, and immobilize the breast. The flat plates can be easily modified for needle localization of tumors and MR-guided biopsy (17). Finally, the SNR of a volume array can be greater than that of a linear or planar array due to the weighting of each voxel based on its position (1, 14).…”

Multiple receive coil arrays are often designed for unilateral imaging of anatomy having bilateral symmetry. A technique is described for extending the utility of such arrays to simultaneously image both bilaterally symmetric anatomical features. A separate, complete multiple receive coil array is placed at each location. Two separate, noncontiguous 3D volumes are then acquired, one at each location, in an interleaved fashion. High-impedance blocking networks are alternately activated and deactivated to minimize coupling between the arrays. It is demonstrated that there is no degradation in image quality when compared to a unilateral exam. A general method for analyzing the interactions between separate multiple coil arrays is presented.
