    【Abstract】 Objective To study the value of ultrasound in diagnosis and differentiation thyroid nodules.Methods Between June2001and June2002，totally97cases who were to undergo surgery and performed ultrasound examination were enrolled in this study.Results On pathology，56cases(65nodules)were diagnosed as benign and41cases(47nodules)as malignant among97cases(112nodules).The sensitivity and specificity of two dimensional ultrasonic diagnosis for thyroid modules are73.1%and82.1%，and the likelihood ratio is4.10.The ratio of periphˉery between benign and malignant of thyroid nodules showed statistical significance(P<0.05).Conclusion The combination of2D characteristic and vascular parttem on CDFI in thyroid nodule can improve the accuracy of differenˉtiation diagnosis.
