Title: Conventional Ultrasound, Real-time Tissue Ultrasonic Elastography and Strain Rate Ratio Elastography in the Diagnosis and Identification of Benign and Malignant Breast Nodules
Abstract: 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(P0.01). 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.
