Clinical study of raise ultrasonic display rate for calcification in breast lesions

Objective To evaluate the value of MicroPure software system in the display of calcification and diagnostic accuracy of breast carcinoma.Methods Sixty-three patients with 68 breast lesions were checked by conventional ultrasound,X-ray and MicroPure software technique.The calcification was described and the lesions were classified with BI-RADS.All cases were pathologically confirmed by biopsy or operation.Results ①Compared to the detection rate for calcification of X-ray,the display rate of conventional ultrasound was 80.6% ,and the display rate of MicroPure software technique was 100%.②The area under the curve of diagnosing benign and malignant of breast lesions was 0.916,0.857 and 0.970 respectively with ultrasound,X-ray and MicroPure software technique.③Three lesions was classified Ⅲ in BI-RADS with conventional ultrasound,and Ⅳ in BI-RADS with MicroPure software.The pathologic results were malignant.Conclusions MicroPure software system obviously raised the ultrasonic display rate of calcification,meanwhile,it raised the diagnostic accurate rate of breast cancer.It especially raised the tendency rate for the patients who were classified between Ⅲ and Ⅳ in BI-RADS.
