彩色多普勒超声对乳腺肿瘤的诊断价值

目的探讨彩色多普勒超声对乳腺肿瘤的诊断价值。方法选取经术后病理证实的乳腺癌119例，乳腺良性肿瘤47例，分析其声像图特征。结果超声诊断乳腺癌111例，误诊8例，良性肿瘤44例，误诊3例。超声诊断乳腺癌的准确性、特异性及敏感性分别为93．4％、84．6％及97．4％，阳性预测值和阴性预测值分别为93．3％和93．6％。边缘毛刺、纵／横比≥1、后方回声衰减、沙砾样钙化、RI等指标在鉴别乳腺良恶性肿瘤中差异有统计学意义（P〈0．01）。结论高频彩色多普勒超声对乳腺癌的鉴别诊断有重要价值。

Diagnostic value of color Doppler ultrasound in breast neoplasms

Objective To study the diagnostic value of color Doppler ultrasound in breast tumors. Methods A total of 119 breast cancers and 47 benign breast tumors were diagnosed by postoperative pathology, and their sonographic characteristics were retrospectively analyzed. Results Breast cancer was diagnosed in 111 cases and misdiagnosed in 8 cases in 119 breast cancers, while benign neoplasm was diagnosed in 44 cases and misdiagnosed in 3 cases in 47 benign breast tumors. The accuracy, specificity, sensitivity, and positive and negative predictive value of ultrasound in the diagnosis of breast cancer were 93.4%, 84.6%, 97,4%, 93.3% and 93.6%, respectively. There were statistical differences in the sonographic features including edge burr, vertical/horizontal ratio ≥ 1, posterior echo attenuation, sand-like calcification, RI and the like between benign and malignant breast tumors （P〈0.01）. Conclusion High frequency color Doppler ultrasound plays an important role in the differential diagnosis of breast cancer.
