The Value of Mammography and High-frequency Ultrasound in Diagnosis of Early Breast Carcinoma

Objective To study the diagnostic value of mammography and high-frequency ultrasound in diagnosis of early breast carcinoma.Methods Sixty-five female patients with breast carcinoma were all confirmed by surgery and pathological examinations. All the patients were examined by the high-frequency ultrasound as well as mammography.Results The positive diagnostic rate,the display of tumor shadow and malignant microcalcification with high-frequency ultrasound and mammography were as follows :64.6%(42/65)and 46%(30/ 65),62%(40/65)and 20%(13/65),40%(26/65)and 20%(13/65)respectively. The difference was considered statistically significant(P0.05). The positive diagnostic rate of high-frequency ultrasound combined with mammography was 83% (54/ 65)。Conclusion High-frequency ultrasound is better than mammography in diagnosis of early breast carcinoma. The combination of two means can increase the positive diagnostic rate of the breast carcinoma.
