Mammographic features of nonpapable breast lesion and clinical application of sterotactic needle core biopsy and sterotactic mammography needle localized biopsy.

Objective To analyze the mammographic features of nonpalpable breast lesion (NPBL),and evaluate the value of Stereotactic needle core biopsy (SCNB) and stereotactic mammography needle localized biopsy (SNLB) for NPBL. Methods Ninety-six cases with breast lesion, which were nonpalpable clinically but could be detected by mammography were studied including 59 cases were examined by SCNB and 37 cases by SNLB. The results of mammographic features of biopsy specimens were compared with pathologic diagnosis. Results Various X-ray features were observed in the 96 cases. Cluster microcalcifications was observed in 47 cases, nodular lesion in 21cases, architecture distortion in 18cases, spicules in 10cases. Of the cases underwent SNLB, 43 cases were pathologically proved as benign lesions and 16 cases as malignant lesions; Of the 37 cases underwent SNLB, 26 cases were pathologically proved as benign lesions and 11 cases as malignant lesions. Conclusion To identify NPBL correctly through mammographic features and properly use of SCNB and SNLB can enhance the rate in early diagnosis of breast cancer and reduce the rate of operation in benign lesions.
