Magnetic Resonance Imaging-Guided Vacuum-Assisted Breast Biopsy: Clinical Results From a Single Center
摘要
PURPOSE. Magnetic resonance imaging (MRI)-guided vacuum-assisted breast biopsy (VAB) is used for suspicious malignant lesions that are detectable only with MRI. The purpose of this study was to investigate the malignancy rate of MRI-guided VAB in a single health center in Taiwan. MATERIALS AND METHODS. A total of 47 MRI-guided VABs for MRI-only lesions, consecutively performed from April 2017 to March 2020 were reviewed. MRI-guided VAB was performed on a 1.5 T-system with a 10 G EnCor device. All lesions detected with MRI could not be detected by mammogram or second-look ultrasonography. RESULTS. All MRI biopsies were technically successful in this study. The 47 lesions were assessed as Breast Imaging Reporting and Data System category 4 or 5. The average lesion size of a mass enhancement was 1.2 cm, and the average lesion size of a nonmass enhancement was 2.6 cm. The median time required to perform the VAB was 40 min. The biopsy was successfully performed without serious complications in all patients. The histopathologic diagnosis was malignant in 12 (25.5%), high risk in 7 (14.9%), and benign in 28 (59.6%) patients. CONCLUSION. MRI-guided breast biopsy is an advisory, well-tolerated, and safe procedure to diagnose MRI-detectable lesions only.
