The ultrasonic diagnosis value of micro-calcification in breast cancer
Objective To explore the diagnosis value of the high-frequency ultrasonography in breast cancer with micro-calcification. Methods 112 cases of breast mass with calcification were tested by high-frequency ultrasonography,which confirmed by postoperative pathology. Emphasis was placed on the size, shape, number and distribution of the calcifications within the mass. And to analysis of the relationship between the calcification types and the nature of the mass. Results 79 of 112 cases were malignant and 33 of 112 cases were benign. Malignant mass with calcification(70.54%, 79/112) were more common than that of benign mass(29.46%, 33/112). The incidence of micro-calcification in malignant mass(92.41%) was significantly higher then benign mass(30.30%). The clusters of micro-calcifications(69.86%) was the main distribution types in malignant mass. The diagnostic sensitivity of breast cancer by microcalcifications was 92.41%. Conclusions High-frequency ultrasonography can effectively display the type of micro-calcifications in the breast mass. The clusters of micro-calcifications is an important index of breast cancer in high-frequency ultrasonography.
