ABSTRACT

Objective To evaluate the clinical application of high-frequency ultrasound-guided Mammotome Breast Biopsy System in the biopsy of breast microcalcification.Methods The sterotactic biopsy of microcalcification in breast was performed under the guidance of high-frequency ultrasonography in 24 patients.Results The location of the lesion was accurately determined in all the 24 patients.Pathological findings showed malignant breast tumors in 3 patients(12.5%) and benign breast diseases in 21 patients(87.5%).The malignant tumors included ductal carcinoma in situ in 2 patients and invasive ductal carcinoma in 1 patient.The benign diseases included cystic lobular hyperplasia in 9 patients,ductal hyperplasia and dilation in 6 patients,galactophore cirrhosis in 5 patients,and intraductal papilloma in 1 patient. Conclusions Use of the Mammotome Breast Biopsy System under the guidance of high-frequency ultrasonography is a safe and effective option for the diagnosis of impalpable breast lesions.
