16层多层螺旋CT技术的引入和广泛应用，以及最近的断层扫描仪，极大地促进了CT血管成像在临床实践中的作用。CT血管成像已成为最先进成像的关键组成部分，应用范围从肿瘤学(如胰腺癌或肾癌的分期)到经典的血管成像(如主动脉瘤和肾动脉狭窄的评估)，以及较新的技术，如冠状动脉成像和外周径流研究。由于每个体数据集中平均有400-1000幅图像，三维后处理对体可视化至关重要。放射科医生现在拥有工作站，通过使用一系列软件程序和处理工具来提供评估这些数据集的能力。虽然不同的系统有独特的能力和功能，但都提供了体绘制和最大强度投影的选项，用于图像显示和分析。这两种后处理技术在临床应用时各有优缺点，放射科医生了解每种技术的使用时间和方式是很重要的。(C)RSNA，2006年。
The introduction and widespread availability of 16-section multi-detector row computed tomographic (CT) technology and, more recently, 64-section scanners, has greatly advanced the role of CT angiography in clinical practice. CT angiography has become a key component of state-of-the-art imaging, with applications ranging from oncology (eg, staging of pancreatic or renal cancer) to classic vascular imaging (eg, evaluation of aortic aneurysms and renal artery stenoses) as well as newer techniques such as coronary artery imaging and peripheral runoff studies. With an average of 400-1000 images in each volume data set, three-dimensional postprocessing is crucial to volume visualization. Radiologists now have workstations that provide capabilities for evaluation of these data sets by using a range of software programs and processing tools. Although different systems have unique capabilities and functionality, all provide the options of volume rendering and maximum intensity projection for image display and analysis. These two postprocessing techniques have different advantages and disadvantages when used in clinical practice, and it is important that radiologists understand when and how each technique should be used.
