高频超声在乳腺微小结节良恶性鉴别诊断中的应用价值

The application of high-frequency ultrasound in differential diagnosis of benign and malignant small breast lesions

目的:探讨高频超声在乳腺微小结节病变良恶性鉴别诊断中的价值。方法:回顾性分析经手术及病理证实的乳腺肿物患者95例112处微小结节(直径≤1 cm),比较良恶性微小结节间在形态、边界、内部回声、微小钙化及内部血流等方面的影像特征,分析图像并总结上述结果在鉴别乳腺良恶性微小结节中的应用价值。结果:乳腺直径≤1 cm的良恶性组微小结节在形态、边界、微钙化灶及血流参数RI值的差异有统计学意义(P<0.05);彩超诊断微小乳癌的敏感度为88.46%,特异度为95%,准确率为91.96%。结论:高频彩色超声对乳腺微小结节良恶性鉴别具有较高的应用价值,对提高微小乳癌确诊率具有重要意义。

Objective： To explore the value of high-frequency ultrasound in the differential diagnosis of benign and malignant small breast lesions. Methods： A total of 95 cases （112 small breast lesions） confirmed by pathology received ultrasonography examinations, and the shape, edge, echoes, microcalcifications blood flow distribution were evaluated. Results： The differences between benign and malignant small breast lesions（≤ 1 cm） in shape, edge, microcalcifieations and RI were of statistical significance （P〈0.05）. The sensibility, specificity and accuracy for diagnosing small breast cancer were 88.46%, 95%, 91.96% respectively. Conclusions： High-frequency ultrasound is valuable in differentiating benign and malignant small breast lesions, and improve the rate of diagnosis in small breast cancer.
