摘要
目的：评价超声（US）和CT检查对甲状腺癌的诊断价值。方法：我们回顾性分析42例甲状腺癌的US和CT表现，42例均行US和CT检查，CT都用对比增强扫描和多平面重建（MPR）来鉴别原发性肿瘤和颈部转移淋巴结。结果：US和CT诊断结果与病理结果进行对比分析。US诊断甲状腺癌的符合率为64.3％, CT为83.3％。对于颈部淋巴结转移诊断US的符合率为75.0％，CT为50.0％。结论：CT对甲状腺癌定性诊断正确率高于US检查，但是US对于怀疑颈部淋巴结转移的晚期病人评价要优于CT。US和CT结合可以提高诊断甲状腺癌的准确性。
Abstract
Objective: To evaluate the diagnostic value of ultrasound(US) and CT for thyroid carcinoma. Methods: The US and CT appearance in 42 cases of thyroid carcinoma were analyzed retrospectively. All the patients had both US and CT examinations. CT with contrast-enhanced scan and multiplanar reconstruction(MPR) were all employed to differentiate primary tumor and metastatic lymph node in the neck. Result: The final diagnostic rate of thyroid carcinoma with US was 64.3％, and CT was 83.3％. The diagnostic rate of cervical lymph node metastasis with US was 75.0％, with CT was 50.0％. Conclusion: CT is more accurate in the diagnosis of thyroid carcinoma than US. But US is better than CT in finding cervical lymph node metastasis of advanced patients. The diagnosis of thyroid carcinoma, when combined US with CT, should be more accurate.
