目的:探讨CT双期增强扫描对甲状腺腺瘤和结节性甲状腺肿鉴别诊断中的价值。资料与方法:回顾性比较25例经手术后病理证实的甲状腺腺瘤和结节性甲状腺肿患者CT平扫及增强扫描结果,并进行分析。结果:25例患者共取出甲状腺结节35枚,其中甲状腺腺瘤18枚,结节性甲状腺肿17枚。腺瘤组平扫CT值30~60 HU,结节性甲状腺肿组平扫CT值25~55 HU,两者差别不明显。腺瘤组增强扫描CT值120~160 HU,结节性甲状腺肿组增强扫描CT值60~100 HU,两者有显著差异。结论:甲状腺CT双期增强扫描对甲状腺腺瘤和结节状甲状腺肿在鉴别诊断上可以提供重要的参考。
Objective: To investigate the value of dual phase CT enhanced CT in the differential diagnosis of thyroid adenoma and nodular goiter. Materials and Methods: CT scan and contrast-enhanced scan of 25 cases of thyroid adenoma and nodular goiter confirmed by pathology were retrospectively analyzed and analyzed. Results: Thirty-five thyroid nodules were removed in 25 patients, including 18 thyroid adenoma and 17 nodular goiter. Adenoma group CT scan 30 ~ 60 HU, nodular goiter group CT scan 25 ~ 55 HU, the difference was insignificant. Adenoma group enhanced CT scan value 120 ~ 160 HU, nodular goiter enhanced CT scan 60 ~ 100 HU, both significant differences. Conclusion: The double-phase enhanced thyroidectomy for thyroid adenoma and nodular goiter in the differential diagnosis can provide an important reference.
