Purpose: To evaluate the calcification retrieval rate, procedure time and radiation dose of stereotactic vacuumassisted breast biopsy made by domestic manufacturer.
Materials and Methods: Between June 2015 and November 2015, 13 women underwent a stereotactic vacuum-assisted breast biopsy for 14 cases of microcalcifications. The calcifications in biopsy specimens were confirmed with specimen mammography and the calcification retrieval rate was examined. The procedure time and radiation dose was compared with the patient data from another stereotactic vacuum-assisted breast biopsy made by foreign manufacturer.
Results: The calcification retrieval rate was 100% (14/14). The histopathology of the 14 lesions was benign for 10 (71.4%), and ductal carcinoma in situ for 4 (28.6%). The time for stereotactic biopsy was mean 21.5 minutes per cases which was significantly longer than foreign manufactured stereotactic biopsy (16.3 minutes, P=0.02), and the mean average glandular dose for whole procedure with domestic device in one women was 8.5 mGy, which showed no significant differences with devices made by foreign manufacturer (7.2 mGy, P=0.114)
Conclusion: Stereotactic vacuum-assisted breast biopsy made by domestic manufacturer is an effective method for evaluation of microcalcifications, with high calcification retrieval rate.
