摘要
[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。
