孤立性肺结节的高分辨CT扫描

High resolution CT scan of solitary pulmonary nodules

目的:探讨孤立性肺结节的高分辨CT扫描诊断方法与效果。方法:采用回顾性研究方法,2015年1月到2016年12月选择在溧阳市人民医院和江苏省人民医院诊治的孤立性肺结节患者60例作为研究对象,所有患者都给予高分辨CT扫描,记录诊断特征与效果。结果:所有患者都完成高分辨CT扫描,恶性结节组的毛刺征、空泡征、分叶征等比例明显高于良性结节组(P<0.05)。良恶性孤立性肺结节的高分辨CT扫描诊断敏感性与特异性为100.0%和77.8%。结论:孤立性肺结节的高分辨CT扫描具有很好的影像学特征,诊断敏感性与特异性都比较好,有很好的应用价值。

Objective To investigate the diagnostic methods and effects of high resolution CT scan in solitary pulmonary nodules. A retrospective study was conducted. From January 2015 to December 2016, 60 patients with solitary pulmonary nodules treated in our hospital were selected as subjects. All patients were given a high resolution CT scan, and diagnostic features and effects were, recorded. Results All patients completed high resolution CT scan, and the proportion of burr sign, vacuole sign and lobulated sign in malignant nodule group was significantly higher than that in benign nodule group （P〈0.05）. The sensitivity and specificity of high resolution CT scan for benign and malignant solitary pulmonary nodules are 100% and 77.8%, respectively Conclusion The high resolution CT scan of solitary pulmonary nodules has very good imaging features, good diagnostic sensitivity and specificity. It has a good application value.
