目的:探讨CT血管征在肺微小结节的诊断及鉴别诊断中的价值。方法:选取2015年6月~2017年6月期间在我院收治的肺微小结节患者50例,按照病理分型结果将其分为恶性病变组和良性病变组,每组各25例,均行CT扫描,观察比较两组患者的诊断敏感度、血管征分型与肺微小结节病变类型的关系。结果:恶性病变组诊断敏感度明显高于良性病变组,组间差异具有统计学意义(P<0.05)。恶性病变组CT血管征阳性者中血管征各型所占比率明显高于良性病变组,P<0.05,差异具有统计学意义。结论:CT血管征可作为肺微小结节的辅助诊断指标,诊断准确率高,在肺微小结节良恶性病变鉴别中具有重要的应用价值。
Objective: To investigate the value of CT angiography in the diagnosis and differential diagnosis of pulmonary nodules. Methods: Totally 50 patients with small pulmonary nodules admitted in our hospital from June 2015 to June 2017 were selected and divided into malignant group and benign group according to the result of pathological classification, 25 cases in each group CT scan was performed to observe and compare the diagnostic sensitivity of the two groups of patients with vascular subtypes and the relationship between the types of pulmonary nodules. Results: The diagnostic sensitivity of malignant lesions was significantly higher than that of benign lesions, the difference was statistically significant (P <0.05). Malignant lesion group CT positive vascular signs in all types of vascular sign was significantly higher than the proportion of benign lesions group, P <0.05, the difference was statistically significant. Conclusion: CT angiography can be used as an auxiliary diagnostic indicator of pulmonary nodules with high diagnostic accuracy, which is of great value in the differential diagnosis of benign and malignant pulmonary nodules.
