慢性阻塞性肺疾病合并肺栓塞患者行螺旋CT增强扫描的影像特点及诊断准确率评价

Image Characteristics and Diagnostic Accuracy of Enhanced Spiral CT in Patients with Chronic Obstructive Pulmonary Disease Complicated with Pulmonary Embolism

目的:评析螺旋CT增强扫描在慢性阻塞性肺疾病合并肺栓塞患者检查的影像特点和准确率。方法:将2017年4月~2020年4月本院收治的50例慢性阻塞性肺疾病合并肺栓塞患者设为观察组,另将同一时间段本院收治的50例单纯肺栓塞患者设为对照组,两组患者均经病理检查确诊,并采用螺旋CT增强扫描,对比观察组和对照组的螺旋CT增强扫描检查结果差异。结果:观察组50例慢性阻塞性肺疾病合并肺栓塞患者经螺旋CT增强扫描检出47例,诊断准确率为94.00%,同病理诊断结果比较差异无统计学意义(P>0.05)。结论:螺旋CT增强扫描在慢性阻塞性肺疾病合并肺栓塞诊断中有着较高的准确率,且该检查方式还能够较清晰地显示患者的肺动脉情况,对于慢性阻塞性肺疾病合并肺栓塞的鉴别诊断也有着重要的意义。

Objective:To evaluate the imaging characteristics and accuracy of enhanced spiral CT in patients with chronic obstructive pulmonary disease complicated with pulmonary embolism.Methods:50 patients with chronic obstructive pulmonary disease complicated with pulmonary embolism treated in our hospital from April 2017 to April 2020 were set as the study group,and 50 patients with simple pulmonary embolism treated in our hospital at the same time were set as the control group.Both patients in the two groups were confirmed by pathological examination and underwent spiral CT enhanced scanning.The results of spiral CT enhanced scanning in the study group and the control group were compared.Results:In the study group,47 cases of 50 patients with chronic obstructive pulmonary disease complicated with pulmonary embolism were detected by spiral CT enhanced scanning,and the diagnostic accuracy was 94.00%.Compared with the pathological diagnosis results,there was no significant difference(P>0.05).Conclusion:Spiral CT enhanced scanning has a high accuracy in the diagnosis of chronic obstructive pulmonary disease complicated with pulmonary embolism,and this examination method can also clearly show the pulmonary artery of patients.It is also of great significance for the differential diagnosis of chronic obstructive pulmonary disease complicated with pulmonary embolism.
