[目的]探讨甲状腺癌术前CT分期的价值。[方法]对38例甲状腺癌病人行术前CT扫描及增强扫描。全部病例均经手术病理证实，其中乳头癌24例，未分化癌5例，髓样癌4例，德泡状癌4例，恶性淋巴瘤1例。分析所有病例CT图像，按照TNM分期法进行甲状腺原发灶CT分期。[结果]CT分期T_12例，准确率40％（to），T_23例，准确率100％（3／3），T_34例，准确率80％（4／5），T_425例，准确96．15％（25／26）。CT分期与病理对照总体符合率为89．47％。T分类诊断过低1例，误诊3例。[结论]CT对甲状腺癌术前原发灶分期有一定的准确性，对T_2、T_3、T_4准确性较高，但对小病灶的定性诊断有一定限制。
[Objective] To explore the value of preoperative CT staging of thyroid carcinoma. [Methods] Preoperative CT scanning and enhanced scanning were performed in 38 cases of thyroid cancer. All cases were confirmed by pathology, including 24 cases of papillary carcinoma, 5 cases of undifferentiated carcinoma, 4 cases of medullary carcinoma, 4 cases of vesicular carcinoma, and 1 case of malignant lymphoma. CT images of all cases were analyzed and CT staging of primary thyroid lesions was performed according to the TNM staging method. [Results] CT staged T_12 cases, accuracy rate 40% (to), T_23 cases, accuracy rate 100% (3/3), T_34 cases, accuracy rate 80% (4/5), T_425 cases, accurate 96.15% (25/26). The overall coincidence rate of CT staging and pathology was 89.47%. The diagnosis of T was too low in 1 case and misdiagnosis in 3 cases. [Conclusion] CT has certain accuracy in the preoperative stage of primary tumors of thyroid carcinoma, and has high accuracy for T_2, T_3, and T_4, but it has certain limitations on the qualitative diagnosis of small lesions.
