摘要：

目的 评价高分辨率CT征象在肺内孤立结节良恶性诊断中的应用价值。方法 择取2013年4月至2016年9月于我院确诊的23例恶性肺内孤立性结节与28例良性肺内孤立性结节患者作为本次研究对象，对比良、恶性肺内孤立性结节患者不同高分辨率CT征象发生情况，评价高分辨率CT征象对肺内孤立性结节良、恶性诊断的准确率。结果 高分辨CT毛刺征、分叶征、血管集束征在恶性肺内孤立性结节患者中出现的次数均显著高于良性肺内孤立性结节患者，差异有统计学意义 （P<0.05）。联合毛刺征、分叶征、血管集束征三种征象中两种或三种进行诊断，两种及三种的CT联合征象的准确率均明显高于单一CT征象，差异有统计学意义（P<0.05）。结论 高分辨CT征象对肺内孤立性结节良恶性诊断准确率高，临床诊断价值高。

ABSTRACT: Objective To evaluate the value of high -resolution CT signs in the diagnosis of solitary pulmonary nodules. Methods Twenty -three malignant solitary pulmonary nodules patients and 28 benign solitary pulmonary nodules patients diagnosed in our hospital from April 2013 to September 2016 were selected as the study objects. The incidence of different high-resolution CT signs of the benign and malignant solitary pulmonary nodules patients were compared, and accuraly rate of high -resolution CT imaging in the diagnosis of benign and malignant solitary pulmonary nodules were evaluated. Results The time of high resolution CT burr sign, lobulated sign, vascular bundle sign in patients with malignant pulmonary solitary nodules were significantly higher than those of benign pulmonary solitary nodules, the differences were statistically significant (P<0.05). In the diagnosis of benign and malignant solitary pulmonary nodules, combined with two kinds or three kinds of the flaming sign, lobulation sign and vascular bundle sign, the accuracy of the two or three CT union signs was significantly higher than those of the single CT signs, the differences were statistically significant (P <0.05). Conclusion High -resolution CT signs has good accuracy rate in solitary pulmonary nodules, which has high clinical diagnostic value.
