摘　　要：目的:探讨CT对甲状腺腺瘤及单发性结节性甲状腺肿的诊断价值。方法:回顾性分别比较26例甲状腺腺瘤和22例单发性结节性甲状腺肿患者的病灶CT平扫均值及增强CT均值、周边正常腺体CT平扫及增强均值,并进行两两统计学分析。结果:腺瘤组平扫平均CT值(59.00±7.94)HU,结节性甲状腺肿组平扫平均CT值(47.86±6.79)HU,两者统计学上差异无显著性意义(P>0.05);腺瘤组增强平均CT值(131.43±24.80)HU,结节性甲状腺肿组增强平均CT值(72.57±21.31)HU,两者统计学上差异有显著性意义(P<0.05);正常腺体平扫及增强CT均值差异均无显著性意义。结论:甲状腺CT增强可以对单发性结节性甲状腺肿和甲状腺腺瘤鉴别诊断提供依据。Objective： To investigate the diagnostic value of CT for mono-nodular goiter and thyroid adenoma. Methods： The mean values of CT plain scan and CT enhancement scan for the thyroid gland of 26 cases with thyroid adeno- rna and of 22 cases with mono-nodular goiter were compared. Statistical analysis was made for all the results. Results： On plain scan, the mean CT value of the thyroid adenoma group was （59.00±7.94）HU, that of the nodular goiter group was （47.86±6.79）HU,after enhancement the former was （131.43±24.80）HU and the latter （72.57±21.31）HU. Between the thyroid adenoma group and the nodular goiter group, there was no difference in the plain scan, P〉0.05, while there was significant difference in the enhancement scan, P〈0.05. Conclusion.. Differential diagnosis between thyroid adenoma and mono-nodular goiter is possible with CT enhancement examination.
