摘　　要：目的 分析64排螺旋CT肺动脉造影诊断肺动脉栓塞的效果。方法 回顾性分析50例行64排螺旋CT肺动脉造影检查的肺动脉栓塞患者的临床资料,观察64排螺旋CT肺动脉造影的影像学结果,以病理结果为金标准,分析64排螺旋CT肺动脉造影的诊断阳性率。结果 影像学结果显示:50例患者的64排螺旋CT肺动脉造影影像学图像类型主要以直接征象和间接征象为主。50例患者均存在不同程度的缺损问题和一定局限性。完全栓塞主要表现为在患者血管远端不会看到造影剂,并且其在血管中断部位无规律可循。病理结果显示,50例患者均为肺动脉栓塞。64排螺旋CT肺动脉造影结果显示,肺动脉栓塞阳性47例,阴性3例。64排螺旋CT肺动脉造影的诊断阳性率为94.00%(47/50)。结论 在诊断肺动脉栓塞过程中使用64排螺旋CT肺动脉造影诊断阳性率高,具有较高的临床应用价值。Objective To analyze the effect of 64-slice spiral CT pulmonary angiography in diagnosis of pulmonary embolism.Methods The clinical data of 50 patients with pulmonary embolism who underwent 64-slice spiral CT pulmonary angiography in our hospital were retrospectively analyzed,and the imaging results of 64-slice spiral CT pulmonary angiography were observed.The diagnostic positive rate of 64-slice spiral CT pulmonary angiography wsa analyzed using pathological results as the gold standard.Results The imaging results showed that the type of 64-slice spiral CT pulmonary angiography images in 50 patients were mainly direct and indirect signs.All the 50 patients had defects and limitations to some extent.Complete embolization is mainly characterized by the absence of contrast media at the distal end of the patient's blood vessel,and its irregular pattern at the site of vascular interruption.Pathological results showed that all the 50 patients had pulmonary embolism.There were 47 positive cases and 3 negative cases in 64-slice spiral CT pulmonary angiography.The diagnostic positive rate of 64-slice spiral CT pulmonary angiography was 94.00%(47/50).Conclusion The use of 64-slice spiral CT pulmonary angiography has high diagnostic positive rate and high clinical application value in the diagnosis of pulmonary embolism.
