螺旋CT在诊断肺动脉栓塞中的应用

Clinical application in diagnosis of pulmonary embolism by spiral CT angiography

目的探讨应用螺旋CT在诊断肺动脉栓塞(PE)中的临床价值。方法选取2008年9月至2009年6月我院收治的PE患者60例,分别应用GE Light Speed 16 16层螺旋CT机扫描检查和传统胸X线片观察,并比较两者的诊断结果。结果螺旋CT检查准确率高于普通X线光片,且无漏诊,其图像上共显示2 658支肺动脉,其中有868支肺动脉显示栓塞,约占总数的32.7%。结论应用螺旋CT进行检查具有扫描速度快,扫描时间短,图像清晰,空间分辨率高,避免漏诊等优点,值得临床推广使用。

Objective Discussion on clinical value of application in diagnosis of pulmonary embolism by spiral CT angiography. Methods Performance of scanning with GE Light Speed16 16-slice Helical CT machine and of observation with traditional chest X-ray film for 60 cases of pulmonary embolism received and cared in our hospital from September 2008 to June 2009, and the comparison of the results from the above two. Results Accuracy rate of inspection with helical CT machine is higher than that with common X-ray films. In addition, the former proved to be without any missed diagnosis. On the image of the former, a total of 2,658 pulmonary arteries were indicated, 868 of which showed sign of embolism, accounting for 32.7% of the total. Conclusion Inspection with helical CT machine proves to be of faster scanning speed, shorter scanning time, clearer image, higher resolution and less probabilities of missed diagnosis compared with traditional method. Thus it is worthy of clinical promotion and application.
