Abstract:
Objective To explore the value of Chinese thyroid imaging reporting and data system(C-TIRADS)combined with intranodular and perinodular stiffness for distinguishing benign and malignant thyroid nodules.Methods Data of routine ultrasound and ultrasonic shear wave elastography(SWE)in 117 patients with thyroid nodules confirmed by fine needle aspiration cytology(FNAC)and/or surgical pathology were retrospectively analyzed.The nodules were classified according to C-TIRADS and SWE parameters of nodules and surrounding 2 mm glands measured with SWE technique,including Young's modulus of thyroid nodules(E)and perinodular glandular(Eshell)(the maximum[Emax/Eshellmax],the mean[Emean/Eshellmean]and the minimum[Emin/Eshellmin]as well as standard deviation[ESD/EshellSD]values).Then receiver operating characteristic(ROC)curve was drawn,and area under the curve(AUC)was calculated to assess the efficacy of C-TIRADS,SWE and the combination for differentiating benign and malignant thyroid nodules.Results Totally 117 thyroid nodules of 117 patients were enrolled,including 50 benign and 67 malignant ones.SWE parameters of malignant thyroid nodules were higher than those of benign ones(all P<0.001).AUC of C-TIRADS for differentiating benign and malignant thyroid nodules was 0.736,with sensitivity of 79.10%,specificity of 68.00%and accuracy of 74.36%.AUC of Emax,Emean,Emin and ESD was 0.816,0.752,0.664 and 0.705,respectively,of Emax was the highest.AUC of Eshellmax,Eshellmean,Eshellmin and EshellSD was 0.834,0.804,0.693 and 0.697,respectively,of Eshellmax was the highest,which was not statistically difference with that of Emax(Z=1.044,P=0.297).AUC of C-TIRADS+Emax and C-TIRADS+Eshellmax was 0.835 and 0.843,respectively,being not significantly different(Z=0.574,P=0.566)but higher than that of C-TIRADS(AUC=0.736,Z=2.510,2.230,both P<0.05),with diagnostic specificity and accuracy both higher than those of C-TIRADS(all P<0.05).Conclusion C-TIRADS combined with intranodular and perinodular stiffness could be used to effectively distinguish benign and malignant thyroid nodules,which might improve diagnostic efficiency of C-TIRDAS.
