摘　　要：目的 探讨CT平扫对单发结节性甲状腺肿与甲状腺腺瘤的鉴别诊断价值。方法 回顾性分析我院和东莞康华医院2006年11月~2013年8月经病理证实的16例单发结节性甲状腺肿与10例甲状腺腺瘤的病例资料。测量患者病灶、周边正常腺体的平扫CT值以及同种疾病病灶与周边正常腺体的CT值比值。结果 结节性甲状腺肿组病灶平扫平均CT值（59.53±4.52）HU,甲状腺腺瘤组病灶的平扫平均CT值为（45.90±8.10）HU,两者统计学上差异有显著性意义（P〈0.05）;结节性甲状腺肿组正常腺体平扫平均CT值（82.21±5.60）HU,甲状腺腺瘤组正常腺体的平扫平均CT值为（102.23±8.99）HU,两者统计学上差异有统计学意义（P〈0.05）;结节性甲状腺肿患者病灶与周边正常腺体的CT值比值显著高于甲状腺腺瘤组[（0.73±0.05）vs（0.46±0.07）,P〈0.05）]。结论 CT平扫对单发结节性甲状腺肿与甲状腺腺瘤的鉴别诊断有重要参考价值。Objective To investigate the differential diagnostic value of CT plain scan for mono-nodular goiter and thyroid adenoma. Methods 16 cases of solitary nodular goiter and 10 cases of thyroid adenoma confirmed by pathology in our hospital and Dongguan Hong Wah hospital from November 2006 to August 2013 were analyzed retrospectively. The CT values of the normal and peripheral normal glands, as well as the CT values of the same disease foci and the surrounding normal glands were measured and compared. Results The average CT values of the lesions in the nodular goiter group and the thyroid adenoma group were （59.53±4.52） HU and （45.90±8.10） HU respectively, and the difference was statistically significant （P 〈 0.05）. The average CT value of normal thyroid gland in patients with nodular goiter and thyroid adenoma group was （82.21±5.60） HU and （102.23±8.99） HU respectively, and the difference was statistically significant （P 〈 0.05）. The lesion/the surrounding normal glands CT ratio of the nodular goiter group were significantly different with that of thyroid adenoma group （P 〈 0.05）. Conclusion CT plain scan in the diagnosis of mono-nodular goiter and thyroid adenoma has important reference value.
