CT检查在甲状腺肿瘤诊断中的价值

Value of CT scan in diagnosis of thyroid tumors

目的分析CT检查在甲状腺肿瘤及肿瘤侵犯中的诊断意义。方法回顾性分析本科2006年7月～2011年7月治疗的200例甲状腺手术患者的临床资料,所有患者均有术后诊断。结果甲状腺癌诊断符合率为95.7%,甲状腺腺瘤诊断符合率为87.5%,结节性甲状腺肿诊断符合率为95.3%。甲状腺癌在颈部侵犯部位包括气管、食管、颈总动脉和颈内静脉,诊断率分别为83.3%、87.5%、87.5%和80.0%。结论 CT在甲状腺肿瘤的诊断中,具有检出率高、敏感性和特异性高的特点,不仅可以作为甲状腺肿块良恶性的鉴别诊断方法,在恶性甲状腺肿瘤的颈部侵犯中也有很高的诊断价值。

Objective To analyze significance of CT scan in diagnosis of thyroid tumor and detecting extrathyroidal invasion of thyroid cancer to adjacent structures.Methods Clinical data of two hundred patients with thyroid masses undergoing surgery in our hospital from July 2006 to July 2011 were retrospectively analyzed.All patients were confirmed by pathology.Results The accuracy rate of thyroid cancer,thyroid tumor and nodular goiter diagnostic were 95.7%,87.5% and 95.3% respectively.The accuracy rate of tracheal invasion,esophageal invasion,common carotid artery invasion and internal jugular vein invasion were 83.3%,87.5%,87.5% and 80.0%.Conclusion CT has a high relevance ratio,sensitivity and specificity in diagnosis of thyroid tumor.It is a valuable tool for thyroid masses differentiating diagnosis and has high diagnosis evaluation of extrathyroidal invasion of thyroid cancer to adjacent structures.
