摘  要：
为探讨常规超声(US)、实时组织弹性成像(UE)及应变率比值弹性成像(SR)在乳腺结节良恶性鉴别诊断中的应用价值。采用回顾性分析95个乳腺结节的US、UE及SR图像方法。常规超声采用BI-RADS分类判断结节性质,UE采用5级评分法判断结节性质,SR测量结节与周围同一水平乳腺的应变率比值,利用ROC曲线比较常规超声、UE、SR的曲线下面积(AUC),判定诊断效能。结果显示,常规超声判断乳腺结节良恶性的敏感度、特异度、准确度分别为:81.7%(49/60)、80.0%(28/35)、81.1%(77/95)。UE判断乳腺结节良恶性的敏感度、特异度、准确度、分别为:86.7%(52/60)、80.0%(28/35)、84.2%(80/95)。良、恶性结节的SR平均值分别为(2.49±0.81)、(3.53±0.95),以3.14作为诊断良恶性结节的最佳截断值时,SR判断乳腺结节良恶性灵敏度、特异度、准确性分别为93.3%(56/60)、91.4%(32/35)、92.6%(88/95);US、UE、SR诊断乳腺良、恶性结节的曲线下面积AUC分别为0.808,0.833,0.924,差异有统计学意义(P=0.000)。由此可知,US、UE及SR均有助于鉴别诊断乳腺良、恶性结节,UE优于US,SR优于UE及US。

摘  要：
To explore the application value of conventional ultrasound(US),real- time elastography(UE)and strain rate ratio elastography(SR) in the differential diagnosis of benign and malignant breast nodules. The ultrasound, UE and SR images of 95 breast nodules were retrospectively analyzed. BI- RADS classfication of US, 5- score evaluation of UE and strain rate ratio of SR was used to evaluate the characteristic of the breast nodules. The ROC under curve area of US, UE and SR was caculated to determine the diagnostic efficacy. The sensitivity, specificity, accuracy of US and UE was 81.7%(49/60), 80.0%(28/35), 81.1%(77/95) and 86.7%(52/60), 80.0%(28/35), 84.2%(80/95), respectively.The sensitivity, specificity and accuracy of SR was(2.49±0.81) for benign nodules and(3.53 ±0.95) for malignant nodules. The cut- off value of SR was 3.14, and sensitivity,specificity and accuracy was 93.3%(56/60),91.4%(32/35), 92.6%(88/95). ROC analysis indicated that AUC was 0.808 for US,0.833 for UE, and 0.924 for SR, which were statistically significant for each other(P<0.01). US, UE and SR are all helpful in differentiating malignant and benign breast nodules, however, UE is better than US, while SR is superior to UE and US.
