摘　　要：目的探讨64层螺旋CT肺动脉造影(CTPA)诊断肺动脉栓塞(pulmonary embolism,PE)的价值。方法回顾分析26例PE患者64层螺旋CT肺动脉造影的影像学表现;以轴位图像为基础,结合多种图像后处理技术综合分析。其中6例患者同时行数字减影血管造影(DSA)检查,进行统计学处理。结果 64层螺旋CT肺动脉造影对叶及叶以上肺动脉的显示率达100%,对段及亚段肺动脉栓塞检出率明显高于DSA,其差异有统计学意义。结论64层螺旋CT肺动脉造影诊断PE优于其它检查,且简便、安全、无创、准确、可靠;可作为首选方法。Objective On the 64-slice spiral CT pulmonary angiography （CTPA） in diagnosis of pulmonary embolism （pulmonary embolism, PE） value. Methods A retrospective analysis of 26 patients with PE findings of 64 slice spiral CT pulmonary angiography images; Based upon the axial image, comprehensive analysis technique combined with a variety of image processing. 6 of them underwent digital subtraction angiography （DSA） examination, statistical analysis. Results The 64-slice spiral CT pulmonary angiography and pulmonary artery on the leaves above the display rate was 100%, The segmental and subsegmental pulmonary embolism detection rate higher than DSA, the difference was statistically significant. Conclusion The 64-slice spiral CT pulmonary angiography in the diagnosis of PE is better than that of other examination, And the simple, safe, noninvasive, accurate, reliable and can be used as the preferred method.
