        ObjectiveTo evaluate the clinical application of high-frequency ultrasound-guided vacuum-assisted biopsy for breast microcalcifications.MethodsSixty-six patients with 70 lesions of microcalcifications detected at mammography underwenthigh-frequency ultrasoundguided vacuum-assisted biopsy from July 2009 to October 2010.All patients were female,aged 24 to 61 years(median age 40 years).Among 70 lesions of microcalcifications,unilateral lesions were 62 cases and bilateral lesions were 4 cases.The clinical factors that affected the success of biopsy were investigated by x2test and Logistic regres-sion analysis.ResultsAmong 70 lesions of microcalcifications,the successful rate of biopsy was 72.9%(51/70).The biopsy successful rate of microcalcifications without and with masses were 65.2% (30/46)and 87.5%(21/34)respectively(x2=3.960,P=0.047).The biopsy successful rate of microcalcifications of maximal diameter more than 5 mm was higher than that of maximal diameter less than 5 mm(88.9%vs.55.9%,x2=9.633,P=0.002).The Logistic regression analysis showed that the types and maximal diameter of microcalcifications were the main factors that affected the success of biopsy.ConclusionThe clinical application of highfrequency ultrasound-guided vacuum-assisted biopsy was an effective option for the diagnosis of breast microcalcifications,especially for the type of microcalcifications with masses and the maximal diameter more than 5 mm.13 refs,2 figs,2 tabs.
