| ［摘要］ 目的 探讨实时组织弹性成像技术应变率比值(SR)诊断乳腺癌的价值。方法 对51例女性患者62个肿块在病理定性前进行常规超声检查，并按照BI-RADS标准对肿块进行分级；以SR 3.08为界点，判断肿块的良恶性，以病理结果为金标准，比较两种方法诊断乳腺癌的准确性。结果 实时组织弹性成像技术应变率比值诊断乳腺恶性肿瘤的敏感度为94.4%(34/36),特异度为92.3%(24/26),准确率为93.5%(58/62)，加权Kappa=0.892，曲线下面积（AUC）为0.864（95%CI 0.801～0.943）；常规超声诊断乳腺恶性肿瘤的敏感度为89.1%（33/37），特异度为88.0%(22/25)，准确率为88.7%(55/62),加权Kappa=0.881，AUC为0.830（95%CI 0.791～0.912）。结论 实时组织弹性成像技术应变率比值作为一种半定量指标，诊断乳腺肿瘤的良恶性简单易行，值得临床推广。 |

| Abstract: |
| ［Abstract］ Objective To explore the value of diagnosis of breast cancer by strain ratio(SR) of real-time tissue elastography technology.Methods Sixty-two breast lesions in 51 female patients were examined with conventional ultrasonic before operation and pathological biopsy, The lesions were graded according to the breast imaging reporting and data system(BI-RADS). Real-time tissue elastography technology was performed to diagnose the breast cancer. The accuracy of the conventional ultrasonic and SR were compared.Results The sensitivity, specificity,and accuracy of SR were 94.4%(34/36), 92.3%(24/26), and 93.5%(58/62); weighted Kappa was 0.892; AUC was 0.864(95%CI 0.801～0.943). The sensitivity, specificity, and accuracy of conventional ultrasonic were 89.1%(33/37), 88.0%(22/25), and 88.7%(55/62) respectively. weighted kappa was 0.881 and AUC value was 0.830(95%CI 0.791～0.912). The accuracy of SR was higher than that of the convertional ultrasonic(P<0.05).Conclusion The accuracy of SR of real-time tissue elastography technology is superior to the conventional ultrasound in the diagnosis of breast malignant lesions. |
