Materials and methods: retrospective analysis of 20 MTC cases of CT and US in the image feature and compared with pathologicalresults and statistics methods diagnosis positive rate. Results: the US diagnosis positive rate was 70% (14 / 20), CT diagnosis positive rate was45% (9 / 20), US-CT combined application, MTC diagnosis positive rate increased to 85% (17 / 20), with serological examination, furthergive the exact diagnosis results. CT can clearly show the thyroid and peripheral blood vessels, trachea anatomical relationship. Conclusion:USand CT diagnosis has the certain difficulty and limitation of MTC, two diagnosis methods combined for mutual confirmation can improvethe diagnostic accuracy (85%). Also by serological examination, make accurate imaging diagnosis and clinical preoperative determinetreatment provide a powerful imaging basis.Key words：CT ；Ultrasonograph；Thyroid ；Medullary thyroid carcinoma【中图分类号】R473【文献标识码】A【文章编号】2096-0867（2015）-08-025-02 　　随着甲状腺肿瘤性疾病发生及发现率越来越高，引起了学者的日益重视。在甲状腺恶性肿瘤中，甲状腺髓样癌（MTC）虽然仅占有 3%～10％，但因其恶性程度较高，易复发、转移，早期诊断较为困难，预后较差，病死率较高，成为大家关注的焦点（1）。因此准确诊断 MTC 成为临床外科医师的迫切需要。 　　目前关于 MTC 的诊断，US 有较明显优势，但在颈淋巴结转移
