孤立性肺结节CT诊断与鉴别诊断

目的探究孤立性肺结节CT诊断与鉴别诊断依据。方法回顾性收集2015年2月~2019年10月我院收治的82例孤立性肺结节患者临床资料及CT资料,通过单因素及多因素Logistic回归分析了解恶性孤立性肺结节的危险因素。结果两组的年龄、性别、结节最大长径、毛刺征、分叶征、胸膜凹陷征、与周围血管关系差异具有统计学意义(P<0.05)。多因素Logistic回归分析结果显示,年龄升高、结节最大长径、毛刺征Ⅰ型、胸膜凹陷征、与周围血管关系Ⅰ型(P<0.05)为恶性孤立性肺结节的独立危险因素。结论年龄升高、结节最大长径、毛刺征Ⅰ型、有胸膜凹陷征、与周围血管关系Ⅰ型提示恶性孤立性肺结节可能较大,可作为参考依据。

CT Diagnosis and Differential Diagnosis of Solitary Pulmonary Nodules

Objective To explore the basis of CT diagnosis and differential diagnosis of solitary pulmonary nodules.Methods Clinical data and CT data of 82 patients with solitary pulmonary nodules admitted to our hospital from February 2015 to October 2019 were collected retrospectively.Risk factors of malignant solitary pulmonary nodules were analyzed by univariate Logistic regression analysis and multivariate Logistic regression analysis.Results Age,sex,maximum length of nodule,spicule sign,foliation sign,pleural sag sign,and relationship with peripheral blood vessels in the two groups were significantly different(P<0.05).Multiariable Logistic regression analysis showed,the age increases,the maximum length to diameter growth,burr nodulesⅠtype,pleural sag,relation with peripheral vascularⅠtype(P<0.05)for malignant isolation independent risk factors of pulmonary nodules.Conclusion Age increases,maximum length of nodule,spicule signⅠtype,pleural sag,relation with peripheral vascularⅠprompt isolation lung nodules may be more vicious,can be used as a reference.
