目的 研究CT和超声对结节性甲 状腺肿的诊断价值。方法 对均于我院行 CT扫描和B超扫描并由临床病理结果诊断 为结节性甲状腺肿100例患者进行回顾性 分析，和病理结果进行对照。超声图像由 我院的超声副主任医师和两个超声诊断医 师进行分析，再和病理结果进行对照。结 果 100例甲状腺结节例患者经过病理检查 均为结节性甲状腺肿，其中合并甲状腺癌 患者24例，CT诊断正确率略高于超声诊 断，差异不具有统计学意义(P>0.05)； CT联合超声诊断正确率明显比CT和超声 组诊断正确率高，差异均具有统计学意 义(P<0.01)。结论 CT和超声扫描各具优 点，因此 CT和超声相组合对结节性甲状 腺疾病患者行扫描诊断正确率能有效提 高。

Objective To study the diagnostic value of CT and ultrasonography in the diagnosis of nodular goiter. Methods A retrospective analysis was performed on 100 patients with nodular goiter diagnosed by CT scan and B ultrasound scan. Ultrasound images were analyzed by ultrasound assistant chief physician and two ultrasound diagnostic physicians, and the results were compared with pathological findings. Results 100 cases were diagnosed as nodular goiter through pathological examination, including 24 cases of patients with thyroid cancer. The correct rate of CT diagnosis was slightly higher than that of ultrasonic diagnosis, but the difference was not statistically significant (P>0.05). The diagnostic accuracy of CT combined with ultrasound was significantly higher than that of CT or ultrasound group, and the difference was statistically significant (P<0.01). Conclusion CT and ultrasound have different advantages, so CT combined ultrasound can improve the diagnostic accuracy rate of patients with nodular thyroid disease.
