Abstract:
Objective To evaluate the diagnostic value of conventional ultrasound and contrastenhanced ultrasound(CEUS) in calcified thyroid nodules.Methods 122 cases of calcified thyroid nodules confirmed by pathology were underwent conventional ultrasound and CEUS.The sensitivity,specificity,positive predictive,negative predictive and diagnostic coincidence rate of conventional ultrasound and CEUS were evaluated.Receiver operating characteristic (ROC) curve was constructed to assess the differential diagnosis value of conventional ultrasound and CEUS in calcified thyroid nodules.Results There were 73 benign and 49 malignant nodules among 122 calcified thyroid nodules.The sensitivity,specificity,positive predictive,negative predictive and diagnostic coincidence rate of conventional ultrasound were 49.98％,76.71％,58.54％,69.14％ and 65.57％,while for CEUS were 89.80％,91.78％,88.00％,93.06％ and 90.98％,respectively.There was statistical difference for each index between the two methods (all P ＜0.05).The area under ROC curve of CEUS was 0.908,which was bigger than conventional ultrasound.Conclusions Compared with conventional ultrasound,CEUS has higher value in differential diagnosis of benign and malignant calcified thyroid nodules.
