摘　　要：目的比较结节性甲状腺肿和甲状腺癌CT特征。方法 41例甲状腺癌患者及41例结节性甲状腺肿患者均接受螺旋CT平扫及对比增强扫描。比较两者的CT特征,包括数量、形态、边缘、内部特点、晕环及钙化及强化值。结果甲状腺癌单发病灶比例(65.85%)、形态不规则比例(78.05%)、边界不清晰比例(75.61%)、内部不均匀的比例(87.81%)、晕环比例(34.15%)和钙化比例(48.78%)均显著高于结节性甲状腺肿,其差异均具有统计学意义(P<0.05)。甲状腺癌与结节性甲状腺肿的CT强化值差异均无统计学意义(P>0.05)。结论甲状腺癌与结节性甲状腺肿CT特征具有一定差异,CT在其鉴别诊断中具有较好的价值。Objective To investigate the CT features of nodular goiter and thyroid cancer. Methods For- ty-one patients of thyroid cancer and 41 patients of nodular goiter patients all underwent spiral CT scan and enhanced scan. The CT features, including number, shape, edge, internal characteristics, halo and calcification of thyroid cancer and nodular goiter were compared. Results In thyroid cancer, the ratio of solitary lesion, irregular morphology, un- clear boundary, internal uneven, halo, calcification were 65.85%, 78.05%, 75.61%, 87.81%, 34.15%, 48.78%, respec- tively, siguifieantly higher than those in nodular goiter （P〈0.05）. There was no siguifieant difference between the CT value of Thyroid cancer and nodular goiter （P〉0.05）. Conclusion CT features of thyroid cancer and nodular goiter has certain differences, and spiral CT has a high value in the differential diagnosis.
