Cross-sectional imaging has become a critical aspect in the evaluation of arterial injuries.\nIn particular, angiography using computed tomography (CT) is the imaging of choice. A variety of\ntechniques and options are available when evaluating for arterial injuries. Techniques involve contrast\nbolus, various phases of contrast enhancement, multiplanar reconstruction, volume rendering,\nand maximum intensity projection. After the images are rendered, a variety of features may be\nseen that diagnose the injury. This article provides a general overview of the techniques, important\nfindings, and pitfalls in cross sectional imaging of arterial imaging, particularly in relation to\ncomputed tomography. In addition, the future directions of computed tomography, including\na few techniques in the process of development, is also discussed.
