ABSTRACT
Objective To evaluate the diagnostic value of gray-scale ultrasound combined with contrast-enhanced ultrasound (CEUS) in thyroid imaging and reporting system ( TI-RADS) 3-5 nodules of American College of Radiology ( ACR) . Methods The 208 patients( 216 nodules) who underwent thyroid contrast-enhanced ultrasound examination from April 2014 to December 2016 were retrospectively analyzed . The ACR TI-RADS classification and contrast-enhanced mode of thyroid ultrasound were evaluated . The benign and malignant thyroid lesions were constructed through the analysis of contrast-enhanced mode of thyroid benign and malignant lesions in the past literature and the preliminary study of our group . Prediction model of gray scale combined with contrast-enhanced ultrasound for lesions were established . Besides ,the sensitivity ,specificity and accuracy of gray scale ultrasound combined with contrast-enhanced ultrasound prediction model for differential diagnosis of benign and malignant thyroid lesions were calculated based on the results of puncture biopsy or surgical pathology as the gold standard . Results Compared with pathological results , the positive predictive value , negative predictive value , accuracy , sensitivity and specificity of gray scale combined with contrast-enhanced ultrasound in evaluating thyroid nodules were 90 .8% ,93 .3% ,91 .2% ,98 .8% and 62 .2% ,respectively . Conclusions Gray-scale ultrasound combined with contrast-enhanced ultrasound can provide clinical value in differential diagnosis of benign and malignant TI-RADS 3-5 thyroid nodules .
