【摘要】：对常规超声诊断为乳腺影像学报告和数据系统(BIRADS)4级并经实时组织弹性成像(RTE)评估的135例患者共147个乳腺病灶进行回顾性分析,对照病理结果,构建应变比值(SR)鉴别乳腺肿瘤良恶性的受试者工作特性曲线(ROC),并评价改良5分法对乳腺良恶性病灶的诊断效能。改良5分法鉴别BI-RADS 4级乳腺病灶良恶性的敏感度82.26%、特异度83.53%、阳性预测值78.46%、阴性预测值86.59%,良性与恶性乳腺病灶的SR值差异有统计学意义(t=8.65,P0.001),SR值测量法鉴别乳腺良恶性病灶的曲线下面积为0.866,当诊断界值为2.365时,诊断价值最高,敏感度为93.5%,特异度为65.9%,表明超声弹性成像技术在鉴别BI-RADS 4级乳腺病灶时有较高的诊断效能。
[Abstract]:Conventional ultrasound diagnosis of breast imaging report and data system BIRADS grade 4 and real time tissue elastography (RTE). A total of 147 breast lesions were retrospectively analyzed in 135 patients. Compared with the pathological results, the strain ratio (SRS) was constructed to differentiate benign and malignant breast tumors from benign and malignant breast tumors. The sensitivity and specificity of the modified 5 score method in differentiating benign and malignant breast lesions from BI-RADS grade 4 breast lesions were evaluated. The sensitivity and specificity of the modified 5 score method for the diagnosis of benign and malignant breast lesions were 82.26 and 83.53% respectively. The positive predictive value was 78.46 and the negative predictive value was 86.59.The SR value of benign and malignant breast lesions was significantly different from that of benign and malignant breast lesions (P 0.001). The area under the curve of SR value measurement for differentiating benign and malignant breast lesions was 0.866. When the diagnostic threshold was 2.365, the diagnostic value was the highest, the sensitivity was 93.5and the specificity was 65.9%. The results show that the ultrasonic elastic imaging technique has a high diagnostic efficiency in differentiating the BI-RADS grade 4 breast lesions.
