Comparative analysis of ultrasonography and pathology in breast masses / 临床与实验病理学杂志

ABSTRACT

Purpose To study the value of the ultrasonic imaging in the diagnosis and differential diagnosis of benign and malignant breast tumor. Methods Color doppler ultrasound examination were conducted in 262 cases of patients with breast tumor. The mor-phology of the tumor, edge, envelope, internal echo, microcalcification, length and breadth ratio, axillary lymph node and blood-flow signals of color doppler in breast tumors were observed and these results were compared with the pathological observation postoperation. Results There were 314 tumors in all cases, the coincidence rate in the diagnosis of benign breast diseases with ultrasonic imaging and pathological diagnosis was 97. 3%, the misdiagnosis rate was 2. 7%. The coincidence rate in the diagnosis of breast malignant tumors with ultrasound imaging and pathological diagnosis was 92. 9%, the misdiagnosis rate was 7. 1%. There were statistically signif-icant differences between benign tumors and malignant tumors in the tumor shape, edge, echo, microcalcification, length and breadth ratio, axillary lymph node imaging characteristics (P<0. 01). Conclusion Ultrasound imaging can be more accurate diagnosis and i-dentification of benign and malignant breast tumors.
