The Operating Technique Of Stereotactic Mammography Aspiration Biopsy

Objective To discuss the operating steps of stereotactic needle core biopsy(SCNB)and evaluate the noteworthy technical factors. Methods SCNB were performed on 36 suspicious breast lesions (32 cases).The main operating steps were as follows: calibrate the device,select and fix patient's position,scan the patients in order ,decide the biopsy route and biopsy with automatic biopsygun. Results The pathologic fingings in 29 suspicious breast lesions for SCNB were consistent with it for postopration,the diagnostic concordance rate and the failure rate of SCNB was 80.6%(29/36) and 8.3%(3/36) respectively.Conclusion SCNB is an advanced valuable technique for the diagnosis of breast lesions.Calibration of the device,fixation of patient's position and selection of proper biopsy route are the key to successful operation of SCNB.
