The introduction of spiral and more specifically multidetector CT scanners has provided unique opportunities in the field of CT angiography. It has also stressed the need of a basic knowledge of post-processing 3D imaging techniques to obtain maximum information of the CT data set. Aim of this article is to give a basic review of technical issues concerning CT angiography, with special attention to 3D imaging techniques such as surface shaded display (SSD), maximum intensity projection (MIP) and volume rendering (VR).
螺旋CT扫描仪，尤其是多排探测器CT扫描仪的引入，为CT血管造影领域带来了独特的机遇。这也凸显了掌握后处理三维成像技术基础知识的必要性，以便从CT数据集中获取最大信息量。本文旨在对CT血管造影的技术问题进行基础综述，特别关注表面阴影显示（SSD）、最大密度投影（MIP）和容积再现（VR）等三维成像技术。
