ABSTRACT
Objective To evaluate the diagnostic value of combined scoring of contrast enhanced ultrasound(CEUS) and ultrasonic elastography(UE) for thyroid imaging reporting and date system(TI RADS) 4 type nodules.Methods The CEUS and UE features of 520 TI RADS 4 type nodules were analyzed retrospectively.The scores of each nodule were evaluated and compared with pathological results and fine-needle aspiration cytology(FNAC).ROC curve was used to compare the diagnostic value of CEUS combined with UE or alone in the differential diagnosis of TI-RADS 4 nodules.Results The sensitivity,specificity,accuracy and area under the curve(AUC) of UE were 82.34%,82.25%,82.31% and 0.841,respectively,when the cut off value of UE score was 4.The sensitivity,specificity,accuracy and AUC of CEUS were 78.63%,65.68%,74.42% and 0.750,respectively,when the cut-off value of CEUS score was 4.The sensitivity,specificity,accuracy and AUC of CEUS combined with UE were 92.31 %,75.74%,86.92% and 0.885,respectively,when the cut-off value of combined score was 6.The sensitivity and accuracy of combined score were higher than those of two other methods,the difference was statistically significant (all P < 0.05),the AUC of combined score was the biggest,it had the highest diagnostic efficacy.Conclusions Combined scoring of CEUS and UE can improve the accuracy in the differential diagnosis of TI-RADS 4 type nodules.
