目的 分析探讨甲状腺结节CT特 点的相关因素。方法 回顾性分析2014年6 月至2015年9月间我院经手术病理证实的 69例甲状腺结节患者，记录良恶性结节的 CT特点并进行多因素分析。结果 69例甲 状腺结节患者共发现84个结节，其中良 性结节59个，恶性结节25个；它们在结 节数目、形态、边界、钙化、强化表现 及腺外侵犯等指标比较存在显著差异(P ＜0.05)。经多因素Logistic分析发现边 界、钙化、强化表现以及腺外侵犯与甲状 腺良恶性结节的鉴别区分存在显著相关性 (P＜0.05)。结论 甲状腺结节的CT表现具 有一定的特征性，认真综合分析其CT征 象、密切结合临床，以此降低误诊风险。

Objective To discuss the influential factors of CT features in thyroid nodule. Methods 69 patients with thyroid nodules diagnosed by pathology from Jun 2014 to Sep 2015 in our hospital were analyzed retrospectively. The CT features of benign and malignant nodules were recorded and compared by using multiple-factor analysis. Results 84 nodules were found in 69 patients with thyroid nodules, including 59 benign and 25 malignant nodules. There were significant differences in the number, shape, border, calcification, enhancement characteristics and periglandular Invasion(P＜0.05). The border, calcification, enhancement characteristics and periglandular invasion were significant features by using Logistic regression analysis. Conclusion The CT features of thyroid nodule has certain characteristic. Analyzing its CT signs carefully and combined with clinical closely, to reduce the risk of misdiagnosis.
