摘要
目的 研究CT对甲状腺结节钙化良恶性的鉴别作用。方法 选择本院2018年7月到2020年6月98例甲状腺结节钙化患者作为研究对象,分析其CT征象,并与病理检查结果进行对比。结果 CT检查显示98例患者中良性结节67例,共钙化结节102个;恶性结节31例,共钙化结节75个。良恶性结节钙化最大径、A/T、钙化部位、钙化边缘、钙化性质、钙化厚薄、钙化连续性比较,差异均有统计学意义(P<0.05);良恶性结节的钙化类型、晕环、密度比较,差异均无统计学意义(P>0.05)。病理检查结果显示,67例良性结节中结节性甲状腺肿29例、甲状腺良性肿瘤7例、甲状腺囊肿9例、甲状腺炎22例;31例恶性结节中甲状腺乳头状癌13例、甲状腺髓样癌4例、甲状腺滤泡状癌8例、甲状腺未分化癌6例。CT检查结果显示,67例良性结节中结节性甲状腺肿31例、甲状腺良性肿瘤7例、甲状腺囊肿6例、甲状腺炎23例;31例恶性结节中甲状腺乳头状癌14例、甲状腺髓样癌4例、甲状腺滤泡状癌7例、甲状腺未分化癌6例。以病理检查结果为标准,CT检查的敏感度为76.47%、特异度为92.19%、阳性预测值为83.87%、阴性预测值为88.06%、准确率为86.73%。结论 CT对甲状腺结节钙化良恶性的鉴别具有较高价值,临床可根据钙化结节的具体征象及病理结果进行结节性质分析。
Objective Tostudy the identification of CT in thyroid nodules with benign and malignant calcification. Methods Ninety-eight patients with thyroid nodule calcification from July 2018 to June 2020 in our hospital were selected as the research objects. Their CT signs were analyzed and compared with the pathological examination results. Results CT examination showed 67 benign nodules among 98 patients,with a total of 102 calcified nodules. 31 cases of malignant nodules,a total of 75 calcified nodules. The difference between the maximum diameter of calcification,A/T,calcification location,calcification edge,calcification nature,calcification thickness,and continuity of calcification in benign and malignant nodules was statistically significant(P<0.05). There was no statistically significant difference in the type,halo,and density of benign and malignant nodules(P>0.05). Pathological examination results showed that among 67 cases of benign nodules,29 were nodular goiters,7 were benign thyroid tumors,9 were thyroid cysts,and 22 were thyroiditis. Among the 31 malignant nodules,13 were papillary thyroid carcinoma,4 were medullary thyroid carcinoma,8 were follicular thyroid carcinoma,and 6 were undifferentiated thyroid carcinoma. The results of CT examination showed that among 67 benign nodules,31 were nodular goiter,7 were benign thyroid tumors,6 were thyroid cysts,and 23 were thyroiditis. Among the 31 cases of malignant nodules,14 were papillary thyroid carcinoma,4 were medullary thyroid carcinoma,7 were follicular thyroid carcinoma,and 6 were undifferentiated thyroid carcinoma. Taking pathological examination results as the standard,the sensitivity of CT examination was 76.47%,specificity was 92.19%,positive predictive value was 83.87%,negative predictive value was 88.06%,and accuracy rate was 86.73%. Conclusion CT has a high value in the differentiation of benign and malignant thyroid nodules with calcification. The nature of nodules can be analyzed based on the specific signs and pathological results of calcified nodules.
