RESUMEN
Objective:To explore the diagnostic value of mammography and ultrasonography(US)in diagnosis of breast disease with microcalcifications.Methods:Seventy-eight cases with breast microcalcifications were detected by mammography.The detection rate of breast microcalcification at US was analyzed.And the sensitivity,specificity and the accuracy of US in diagnosis breast disease with microcalcifications was compared with these of mammography.Results:The detection rate of breast microcalcification was 66.7%,And US depicted more malignant(87.5%)than benign microcalcification(33.3%).The sensitivity specificity and accuracy of US was 68.7%、83.3%、 74.3%respectively,and the sensitivity specificity and accuracy of mammography was 72.9%、 73.3%、75.6%respectively,there were no significant difference between the two methods.The sensitivity,specificity and accuracy of the combined the two methods was 89.6%,90.0%,92.3% respectively.Conclusion:US can effectively detect and identify the breast microcalicications.The combination can improve the assessment of breast disease with microcalicications,and has a significant clinical practical value in diagnosis of early breast cancer.
RESUMEN
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(P
