| Popis: | This prospective study evaluates the feasibility of the magnetic resonance (MR)-guided vacuum-assisted breast biopsy with a handheld vacuum-biopsy system and documents the biopsy results with MR mammography 24 h after the procedure. MR-guided biopsy was undertaken in 33 patients with 34 lesions on dynamic MR mammography. The interventions were performed with the handheld 10-gauge Vacora vacuum-biopsy system. In all cases, dynamic MR mammography was performed 24 h after the procedure to determine the extent of the lesion removal and to identify the lesions that were missed. In 5/34 (14.7%) lesions, biopsy was not performed because no suspicious lesion was identified on the day of biopsy. In 25/29 (86.2%) lesions, the biopsy was successfully performed with a complete removal in 4/29 (13.8%) and a partial removal of 21/29 (72.4%) lesions. In 4/29 (13.8%) interventions the lesion was missed with the biopsy. In one case, histopathology after surgical excision revealed ductal carcinoma in situ. Histopathology revealed 9/29 (31%) malignant and 20/29 (68.9%) benign lesions. MR-guided vacuum-assisted breast biopsy with the handheld Vacora vacuum-biopsy system is technically feasible in most cases. MR mammography 24 h after the biopsy should be performed in those cases in which the biopsy success is unclear immediately after the procedure. |
