64层螺旋CT肺动脉造影（CTPA）诊断肺动脉栓塞的价值

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.
