目的 :探析CT动态增强扫描诊断早期肺癌的临床效果。方法 :选取我院2014年1月-2016年7月收治的45例肺部孤立性肺结节患者为研究对象,所有患者均给予CT动态增强扫描与病理检查,对比2种检查的诊断结果及早期肺癌患者和良性肺结节患者的CT参数。结果:病理检查显示,早期肺癌40例,肺炎2例,肺结核3例;CT动态增强扫描检查显示,早期肺癌39例,肺炎3例,肺结核3例,二者对比无明显差异(P>0.05),诊断符合率是95.6%。在血容量、表面渗透性、血流量、通过时间方面,早期肺癌患者与良性肺结节患者差异明显(P<0.05)。结论 :在早期肺癌诊断中,CT动态增强扫描检查诊断的准确性较高,可在临床中推广应用。
Objective: To investigate the clinical effect of CT dynamic contrast-enhanced scan in the diagnosis of early stage lung cancer. Methods: Forty-five patients with pulmonary solitary pulmonary nodules admitted from January 2014 to July 2016 in our hospital were enrolled in this study. All patients underwent CT dynamic contrast-enhanced scanning and pathological examination. Comparing the diagnostic results of the two kinds of examinations and CT Parameters of Patients with Early Lung Cancer and Benign Pulmonary Nodules. Results: Pathological examination showed that there were 40 cases of early lung cancer, 2 cases of pneumonia and 3 cases of tuberculosis. CT dynamic contrast-enhanced scanning showed that there were 39 cases of early lung cancer, 3 cases of pneumonia and 3 cases of tuberculosis. There was no significant difference between the two groups (P> 0.05) , The diagnostic coincidence rate was 95.6%. In terms of blood volume, surface permeability, blood flow and passage time, the difference between early lung cancer patients and benign pulmonary nodules was significant (P <0.05). Conclusion: In the early diagnosis of lung cancer, the diagnostic accuracy of CT dynamic contrast-enhanced scan is high and can be widely applied in clinical practice.
