MSCT对甲状腺癌的诊断价值分析

Value of multi-slice Spiral CT in the Diagnosis of Thyroid Carcinoma

目的:探讨MSCT对甲状腺癌的诊断价值。方法:回顾性分析22例经手术病理证实的甲状腺癌的MSCT资料,主要对原发病灶和颈部转移淋巴结情况进行分析,并与手术及病理结果对照。结果:所有病例MSCT均见肿块,平扫为等或混杂密度,边界不清,呈浸润性生长,增强扫描不均匀强化,并向邻近组织侵犯,颈部常可见肿大淋巴结。结论:甲状腺癌的MSCT表现具有一定特征性,MSCT能准确判断甲状腺癌是否侵犯周围组织器官,为临床制定治疗方案提供重要依据。

Objective：To study the value of multi-slice spiral CT （MSCT） in the diagnosis of thyroid carcinoma. Methods：The MSCT findings of 22 cases with thyroid carcinoma proved by surgery and pathology were analyzed retrospectively. The image manifestations of primary neoplasm and metastatic lymphadenopathy of neck were correlated with the surgery and pathology findings. Results： All of the thyroid masses were revealed on MSCT,showing iso- or heterogeneous attenuation on plain scan, with ill-defined margin and infiltration. After contrast administration,heterogeneous enhancement and invasion into adjacent tissue were showed, metastatic lymphadenopathy in the neck could often be seen. Conclusion： Characteristic MSCT findings of thyroid carcinoma as well as the adjacent tissue/organ invasion could often be assessed, which could provide important information for clinical treatment planning.
