Title: The Value of Quantitative Assessment in Benign and Malignant Thyroid Nodules
Abstract: Objective: To evaluate elasticity score and the critical point of strain ratio by ultrasonograms in differential diagnosis of thyroid nodules.Methods: Elasticity imaging was used to examine 78 cases of patient with 122 thyroid nodules.The elasticity scores and strain ratio were retrospectively reviewed and compared with pathology.According to the pathological findings are divided into benign and malignant groups.Results:(1)An elasticity score of 1-3was observed in 90 of 122 nodules,while a score of 4 and 5 in the rest of 32 nodules,which displayed a sensitivity of 75%,a specificity of 82% and a accuracy of 80%;(2) strain ratio: Of the 122 lesions,90 were benign and 32were malignant.The average of strain ratio of benignnodules was 2.34+1.02,while that of malignancy was 4.15+1.09;(3) According to the ROC curve,the critical point was 3.30,which displayed a sensitivity of 81%,a specificity of 90% and a accuracy of 87%.The area under the receiver operating characteristic curve was 0.831.Conclusion: The strain ratio and elasticity score in elasticity images is helpful in the differential diagnosis of thyroid lesions.
