CT angiography is an emerging technique for noninvasive evaluation of peripheral vascular disease. CT was first used to evaluate the peripheral vasculature in the early 1990s. Single-detector spiral CT scanners were limited by their inability to cover the whole vasculature from the diaphragm to the feet quickly enough to track a contrast bolus. These limitations were overcome with the advent of multislice CT scanners in 1998.1 MSCT images are comparable to those obtained with catheter angiography.
