MSCT angio advances in peripheral vessels

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 (Figure 1).
