甲状腺结节105例多层螺旋CT表现与病理对照分析

目的：总结105例甲状腺结节的CT表现及病理对照,探讨甲状腺结节良恶性CT诊断征象.方法;对照回顾性分析105例（220个结节）甲状腺结节的CT表现,包括结节密度、囊变程度、边缘、钙化、强化程度,CT表现与病理结果进行对比分析.结果：对照病理结果,CT在甲状腺结节砂粒样钙化、边缘、数目、囊变程度、结节强化程度方面,良恶性结节之间差异有统计学意义（P＜0.05）;甲状腺良恶性结节在密度及数目上无统计学差异（P＞0.05）.结论：多层螺旋CT在评估甲状腺结节性质具有重要临床意义.

MSCT features of thyroid nodules and correlation with pathology

Objective：To summarize the MSCT features of 105 cases of thyroid nodules and the correlation with pathology,and to explore the CT signs of benign and malignant thyroid nodules.Methods：The CT features of 105 cases of thyroid nodules（220 nodules） were analyzed retrospectively including density of nodules,cystic formation,degree of enhancement,margin of nodules,and correlated to pathology.Results：Compared with pathology,the CT features of sand-like calcification,cystic formation,and degree of enhancement had statistical significance in the differentiation between benign and malignant lesions （P＜0.05）.The CT features of density and number of nodules had no statistical significance in the differentiation between benign and malignant thyroid nodules（P＞0.05）.Conclusion：There is important value of MSCT in the differentiation of the nature of thyroid nodules.
