Value of thyroid imaging reporting and data system combined with contrast enhanced ultrasound in differential diagnosis of benign and malignant thyroid nodules
摘要
Abstract
Objective To investigate the diagnostic value of thyroid imaging reporting and data system( TI-RADS) combined with contrast enhanced ultrasound( CEUS) in differentiating benign and malignant thyroid nodules.Methods Ninety-one patients with thyroid nodule involving 127 nodules were examined by conventional ultrasound and CEUS respectively.All of the nodules were graded by TI-RADS based on their two-dimensional ultrasound features, and then were confirmed by their pathologic findings after operation.The pathologic findings were taken as golden standard to assess the values of TI-RADS,CEUS and their combination in the diagnosis of thyroid cancer.Results Most of the images of CEUS enhancement pattern for malignant thyroid nodules showed early hypoenhancement,heterogeneous enhancement and no surrounding ring enhancement.Based on these features as the diagnostic standard of malignant thyroid nodules, the sensitivity,specificity and coincidence rate for the diagnosis of early hypoenhancement were 73.08%(19/26),80.20%(81/101) and 78.74%(100/127),respectively,of heterogeneous enhancement were 73.08%(19/26),75.25%(76/101) and 74.80%(95/127),respectively,and of no surrounding ring enhancement were 96.15%(25/26),32.67%(33/101) and 45.67%(58/127),respectively.Based on TI-RADS Grade 5 as malignants,the sensitivity,specificity and coincidence rate of TI-RADS for the diagnosis of malignant thyroid nodules were 46.15%(12/26), 99.00%(100/101) and 88.19%(112/127),respectively;of TI-RADS combined with CEUS were 80.76%(21/26),96.04%(97/101) and 92.91%(118/127),respectively.TI-RADS combined with CEUS had a significantly higher accuracy in the diagnosis of malignant thyroid nodules compared with TI-RADS or CEUS alone(P<0.05).Conclusion TI-RADS might give a preliminary and standard risk judgment on malignant thyroid lesions,the use of CEUS might further improve the efficiency in the differential diagnosis of benign and malignant nodules,and the combination of TI-RADS and CEUS might improve the efficiency in the preoperative diagnosis of thyroid nodules.关键词
