CT环状钙化在甲状腺良恶性结节诊断和鉴别诊断中的价值

The Value of CT Annular Calcification in Diagnosis and Differential Diagnosis of Benign and Malignant Thyroid Nodules

目的:探究CT环状钙化在甲状腺良恶性结节诊断和鉴别诊断中的价值,为临床诊断甲状腺良恶性结节提供指导。方法:以2016年8月12日至2017年8月25日来我院接受救治的56例甲状腺结节患者(均经手术病理证实)作为观察对象,对56例甲状腺结节患者均实施CT诊断,以手术病理结果为诊断金标准,并将CT诊断结果和手术病理检查结果进行比较,研究对比CT环状钙化在甲状腺良恶性结节诊断和鉴别诊断中的价值。结果:CT对甲状腺良恶性结节的诊断敏感度、特异度、准确度分别为94.87%、88.24%、92.86%,将诊断结果和手术病理诊断结果进行比较发现,两者差异无统计学意义,P>0.05;甲状腺良性结节和甲状腺恶性结节之间的增强后边缘清晰、高强化结果存在统计学意义,P<0.05。结论:CT环状钙化对诊断甲状腺良恶性结节具有较显著的效果,敏感度、特异度以及准确度均较高,值得各医疗机构推广应用。

Objective： To explore CT annular calcification in the value of diagnosis and differential diagnosis of benign and malignant thyroid nodules,and provide guidance for clinical diagnosis of benign and malignant thyroid nodules. Methods： From August 12,2016 to August 25,2017,56 cases of thyroid nodules treated in our hospital were confirmed by surgery and pathology. 56 cases of thyroid nodules were diagnosed by CT. The operative pathology results were the gold standard for diagnosis. The results of CT diagnosis and surgical pathology were compared. The value of CT annular calcification in diagnosis and differential diagnosis of benign and malignant thyroid nodules were compared. Results： The sensitivity,specificity and accuracy of CT in the diagnosis of benign and malignant thyroid nodules were 94. 87%,88. 24% and 92. 86% respectively.Comparing the diagnostic results with the results of pathological diagnosis,there was no significant difference between the two groups（ P〉0.05）. There was a significant difference between enhanced thyroid nodules and thyroid nodules with enhanced margins and high enhancement results（ P〈0.05）. Conclusion： CT cyclic calcification has a significant effect on the diagnosis of thyroid benign and malignant nodules,with high sensitivity,specificity and accuracy,which is worthy of the application and promotion of various medical institutions.
