甲状腺癌的B超与CT检查表现及意义

Diagnostic value of computer tomography and ultrasound in diagnosis of thyroid carcinoma

目的:探讨B超及CT检查对甲状腺癌的诊断价值。方法:回顾性分析189例甲状腺癌患者的B超及CT检查,了解甲状腺癌在B超及CT检查中的表现,并比较两者的优缺点。结果:B超及CT检查对甲状腺肿快的检出率为100%,B超诊断TC的符合率为50.7%,CT为81.6%,CT诊断颈部淋巴结转移的符合率为51.4%,B超为74.0%。结论:CT对甲状腺癌定性诊断正确率高于B超检查,B超发现颈部淋巴结转移要优于CT,B超应作为检查颈部肿块的首选办法。

Objective：To evaluate the diagnostic value of the CT and ultrasound （US） for thyroid carcinoma. Methods： We analyzed 189 cases of thyroid carcinoma with CT and US appearance. The images were reviewed for primary lesion and metastatic lympadenopathy on the neck. Results： The recognize rate of CT and ultrasound in thy- roid carcinoma were both 100%. The final diagnosis rate of US in thyroid carcinoma was 50.7% , and CT was 86.1%. The diagnoisic of metastatic lympadenopathy on the neck with US was 74.0%, with CT was 51.4%. Con- clusion ： CT is more accurate in the diagnosis of thyroid carcinoma than US, but US is quite well in finding metastatic lympadenopathy on the neck than CT. US should be used as the first examination method for thyroid carcinoma.
