螺旋CT对甲状腺癌的诊断价值

目的:评价螺旋CT对甲状腺癌的诊断价值。方法:回顾性分析89例经手术和病理证实的甲状腺癌的螺旋CT资料。结果:89例甲状腺癌的主要CT表现为密度不均88例,边界不清68例,不规则坏死67例,囊性变39例,瘤周出现“半岛状”强化结节25例,囊壁“乳头状”强化结节9例,钙化55例,增强强化不均73例,CT判断甲状腺癌侵犯气管、食管、颈动脉鞘和颈部或锁骨上淋巴结肿大转移分别为:29例、21例、16例和26例,手术证实分别为:26例,17例、14例和26例。CT对甲状腺癌诊断正确率94.4%(84/89)。结论:CT对甲状腺癌的诊断可靠,能发现甲状腺癌外侵与否,能帮助临床术前分期,CT检查是必要的。

The Value of Spiral CT on Thyroid Carcinoma Diagnosis

Objective To evaluate the value of spiral CT scan on diagnosis the carcinoma of thyroid.Methods Spiral CT findings on 89 cases of thyroid carcinoma with the surgical-pathological were analysed retrospectivily.Results The CT findings in 89 cases of thyroid carcinoma were:inhomogeneous density(n=88),vague margin(n=68),abnormity necrosis(n=67),cystic changes(n=39),“peninsula” enhancing tubercles around the tumour(n=25),“mastoid” tubercles around the tumour(n=9),calcification(n=55),inhomogeneity enhanced(n=73).The thyroid carcinoma invaded the trathea(n=29),esophageal(n=21),carotid sheath(n=16),lymphadenopathy(n=26) according to CT compared with n=26,n=17,n=14 and n=26 according to surgical-pathological.The accuracy of thyroid carcinoma diagnosis by CT were 94.4%(84/89).Conclusion Spiral CT scan examination on thyroid carcinoma and estimate it's extra-thyroid invasion were credible.CT are the important methods in evaluating the stage of thyroid carcinoma preoperation.CT scan was useful for thyroid carcinoma peroperation.
