Abstract：Objective To assess the value of thyriod imaging reporting and data system (TI-RADS), contrast-enhanced ultrasound (CEUS), combination of TI-RADS and CEUS in diagnosis of thyroid nodules.Methods The TI-RADS and contrast-enhanced ultrasound signs of 274 thyroid nodules in 196 patients (141 malignant, 133 benign) were retrospectively analyzed.The lesions were defined as five categories of the benign, probably benign, equivocal, probably malignant and malignant.The results of thyriod imaging reporting and data system, contrast-enhanced ultrasound, combination of TI-RADS and CEUS were compared with pathology.By using the definitive diagnosis and the five level of suspicion categories, receiver operating characteristic (ROC) curve was drawn for the results of thyriod imaging reporting and data system, contrast-enhanced ultrasound, combination of TI-RADS and contrast-enhanced ultrasound.Results The area under the ROC curve of combination of TI-RADS and CEUS (0.917±0.019) was larger than that of thyriod imaging reporting and data system (0.826±0.026) and contrast-enhanced ultrasound (0.851±0.025).The increases in the areas were significant (P=0.000, 0.000, 0.000).Conclusion TI-RADS and contrast-enhanced ultrasound are important in diagnosis of thyroid nodules.Combination of TI-RADS and contrast-enhanced ultrasound results in an increase in diagnostic accuracy of thyroid cancer.
