目的：比较研究多层螺旋CT后处理技术显示冠状动脉狭窄的形态与范围。方法：采用飞利浦多层螺旋CT工作站对随机抽取的120例病人冠状动脉采集图像进行重组，由2位影像医师比较多平面重组（multi-planar reformation，MPR）和CT仿真内窥镜（CT virtual endoscopy，CTVE）两种后处理技术对粥样硬化斑块形态的显示能力，同时比较MPR、曲面重建（curved planar reformat，CPR）和容积再现技术(volume rendering technique,VRT)在显示狭窄范围上的差异。结论：多层螺旋CT冠状动脉成像常用的后处理方法中， MPR血管轴位图最适合进行冠状动脉狭窄形态的研究；CPR最适合研究血管狭窄的范围。

Objective: To study the multi-detectorspiral computed tomographic coronary angiography post-processing techniques that showed the differences in the ability of coronary artery stenosis. Methods: Use the Philips iCT for image reconstruction,120 patients who underwent multislice spiral CT coronary angiography (computed tomographic coronary angiography, CTCA) were randomly selected. Two radiologists compared MPR with CTVE about the abilities of the coronary atherosclerotic plaques` morphology, and finded one method of MPR, CPR and CTVE, which is the best about the distribution of coronary atherosclerotic plaques. Conclusion: In many postprocessing technique of multislice CT, MPR vessels cross-section was the best suitable for the morphology of coronary atherosclerotic plaques, CPR was for the distribution.
