Abstract:
Objective To evaluate the diagnostic value of ultrasonography (USG) and contrast-enhanced computer tomography (CT) for thyroid carcinoma.MethodsThe results of the review of the preoperative CT and those of the original US reports were compared with the histopathologic results in 73 cases of thyroid carcinoma who underwent radical operation and central compartment dissection from November 2009 to November 2011.ResultsThe final diagnostic rate of thyroid carcinoma with USG was 69.9％,CT of that was 80.8％.There were no significant difference between them (P =0.077).The diagnostic rate of metastatic lymph node in the central compartment with USG was 61.6％,positive predictive value was 64.0％,negative predictive value was 60.4％.The diagnostic rate of metastatic lymph node in the central compartment with CT was 67.1％,positive predictive value was 61.7％,negative predictive value was 76.9％.There were not significant difference between them(P =0.848,P =0.152,P =0.489).Conclusion There was no significant difference between USG and CT in The final diagnostic rate of thyroid carcinoma and its lymph node metastasis in the central compartment.
