摘　　要：目的:采用120 k V、80 m A低剂量扫描甲状腺,探讨其对结节性甲状腺肿(NG)和甲状腺癌(TC)的诊断价值。方法:选取NG和TC共47例,行120 k V、80 m A低剂量扫描甲状腺,分析NG与TC的CT表现。结果:TC 15例,NG 32例。19例为单发病灶,左叶9例,右叶8例,2例累及峡部。28例为多发病灶,其中3例TC周围软组织受侵。TC与NG的甲状腺大小、密度、部位、各期CT值、包膜有无、微小钙化、淋巴结肿大差异均无统计学意义(均P>0.05);病灶边缘清楚与否差异有统计学意义(P<0.05)。结论:低剂量CT诊断TC和NG具有可行性,边缘清楚与否是鉴别TC和NG的特征性表现。Objective：Using 120 kV,80 mA low-dose thyroid scan,analyzing diagnostic value of LDCT scan in nodular goiter and thyroid carcinoma. Methods：Retrospective analysis of the 64 slice spiral CT scanning of thyroid,tube voltage 120 kV,tube current of 80 mA,analysis of nodular goiter and thyroid carcinoma CT. Results：Thyroid carcinoma in 15 cases,nodular goiter in 32 cases. 19 cases were single lesions,9 cases of left lobe,right lobe in 8 cases,2 cases involving the isthmus. 28 cases were multiple lesions,including 3 cases of peripheral soft tissue invasion. There was no statistical significance in the size, density,po- sition and CT value,capsule,minor calcification,lymphadenectasis （P〉0.05）. Whether the lesions had clear margin was statisti- cally significant （P〈0.05）. Conclusion：Diagnosis of thyroid carcinoma and nodular goiter with low dose of CT is feasible,and the margin is clear or not is the characteristic manifestation of thyroid carcinoma and nodular goiter.
