摘要
目的:评价多层螺旋CT在肺动脉栓塞临床诊断中的应用价值。方法:选取61例肺动脉栓塞患者作为研究对象,对61例患者实施多层螺旋CT诊断,统计本组患者肺动脉或分支栓塞的检出率,观察本组患者的CT表现。结果:结合其他影像学诊断方法进行诊断,本组61例患者累计出现201支肺动脉或分支栓塞,多层螺旋CT诊断的肺动脉或分支栓塞检出率为94.03%。多层螺旋CT影像学资料显示本组患者中,60例患者有明显的肺动脉栓塞直接征象(肺动脉内充盈缺损),1例患者无明显的肺动脉栓塞直接征象,54例患者有明显的间接征象(“马赛克征”、支气管动脉扩张、肺动脉高压等),诊断准确率为96.72%。结论:多层螺旋CT诊断肺动脉栓塞,无创、操作简单、能够直接显示肺实质情况,图像资料清晰,诊断准确率高,具有临床应用价值。
Objective:To evaluate the clinical value of multi-slice spiral CT in the diagnosis of pulmonary embolism.Methods:61 cases of pulmonary artery embolism was the subjects.61 patients were diagnosed with multislice spiral CT.The detection rate of pulmonary artery or branch embolism in this group was statistically analyzed,and the CT manifestations of the patients were observed.Results:combined with other imaging diagnosis methods,61 patients in this group had 201 pulmonary artery or branch embolism,and the detection rate of pulmonary artery or branch embolism was 94.03%by multislice spiral CT.Multi slice spiral CT imaging data showed that 60 patients had obvious direct pulmonary artery embolization(pulmonary artery filling defect),1 patients had no obvious pulmonary artery embolization,54 patients had obvious indirect signs("mosaic sign",branched tracheal artery dilatation,pulmonary arterial hypertension,etc.).The accuracy rate is 96.72%.Conclusion:the diagnosis of pulmonary embolism by multi-slice spiral CT is not invasive,simple and can directly display the pulmonary parenchyma.The image is clear and the diagnostic accuracy is high.It has the value of clinical application.
