Abstract:
Objective To evaluate the feasibility of MRI-guided vacuum-assisted breast biopsy in domestic clinical prac tice.Methods A total of 45 patients with 45 suspicious breast lesions were examined with MRI-guided vacuum assisted bi opsy.The complications were observed.And the followed-up was performed.Results In 45 suspected breast lesions,43 lesions (43/45,95.56%) were successfully sampled under MRI-guided vacuum-assisted biopsy and the pathologic diagnosis was obtained.For another 2 lesions (2/45,4.44%),the pathology diagnosis were not obtained.The time to perform MRI-guided biopsy was (45.87±8.41)min for one lesion.The 5 malignant lesions (5/45,11.11%) confirmed by biopsy pathology were consistent with postoperative pathological results.For the 38 benign lesions (38/45,84.44%) confirmed by biopsy pathology,there was no malignant performance found in MRI follow-up for 6 months.Because of successful MR imaging-guided core biopsy findings,the clinic treatments were changed in 14 patients (14/45,31.11%).Five cases (5/45,11.11%) with malignant tumors were diagnosed early.The surgical biopsy was avoided in 9 benign cases (9/45,20.00 %) who suspected as malignant.In all 45 patients,no complications occurred,such as hematoma and infection.Con clusion MRI-Guided vacuum-assisted breast biopsy is sufficient and safe for obtaining histologic proof of lesions,and plays an important role in guiding clinic treatment of some lesions visible only by MRI.
