MDCT has improved imaging of the arteries in the lower extremities because of its fast scan times, high spatial resolution, and increased anatomic coverage, allowing cost-effective assessment of long vascular segments with higher spatial, contrast, and temporal resolution. To use this powerful tool to full advantage in evaluating diseases and injuries of vessels in the lower extremities, certain aspects of its use must be mastered, such as the timing of contrast administration and generation and the use of high-quality 3-D renderings and multiplanar reformations. CT angiography has become a routine means of evaluating a broad spectrum of arterial abnormalities in the lower extremities.
