Abstract: Objective To evaluate the diagnostic accuracy of ultrasonography (US) and CT for thyroid masses. Methods Seventy-one patients with thyroid masses (13 with malignant and 58 with benign tumors) confirmed by operation and pathology were collected. The apprearances of CT and US before operation were analyzed. The apperanecs of CT and US, including the clean edge of masses, calcification and cystic degeneration necrosis were compared with those of pathologic findings. Results The numbers, cystic changes, configuration, verge, calcify and enlarge cervical lymph nodes of thyroid lesions had statistical difference in CT and US (P＜0.05). There was also difference in the internal echo, ring of halo on US and the sign of halo on plane CT (P＜0.05). The edge of thyroid mass could be displayed more clearly with US than CT (P＜0.05), however, it was similar with CT in the display of calcify and cystic changes (P＜0.05). Conclusion Both CT and US can display thyroid mass clearly. Combing of CT and US could improve the accuracy rate of diagnosis.
