摘　　要：目的分析孤立性甲状腺结节的CT表现,评价CT扫描在孤立性甲状腺结节良恶性鉴别诊断中的价值。方法与病理结果对照分析75例孤立性甲状腺结节的CT表现特点。结果在结节边缘不清、微小钙化等方面,良恶性结节有显著性差异(P<0.05),对恶性结节诊断的敏感度分别为50.0%、40.0%,特异度分别为89.1%、92.7%,准确性分别为90.8%、88.1%。完整包膜在甲状腺良性结节中显示率为25.5%。囊性不强化在结节性甲状腺肿显示率为42.1%。结论边缘不清、微小钙化是甲状腺恶性结节特点,完整包膜是甲状腺良性结节特点,囊性不强化是结节性甲状腺肿的特殊表现。Objective To evaluate the differential diagnostic value of CT features of solitary thyroid nodules.Methods This study has reviewed the CT features of thyroid nodules by using tissue diagnosis as the reference standard.Results statistically significant（P0.05）findings of malignant were ill-margin,micro-calcification,sensitivity was 50.0%,40.0% respectively,specificity was 89.1%、92.7% respectively,accuracy was 90.8%、88.1% respectively.Conclusion The ill-margin and micro-calcification are the characteristic features of malignant nodules,and the capsule and cystic are the characteristic features of benign nodules.
