Advances in CT angiography for peripheral arterial disease

Multidetector CT scan (MDCT) has revolutionized the diagnosis of peripheral arterial disease. The most recent generation of CT scan systems increases the number of detector arrays, which allows further increases in volume coverage and acquisition of large volumes rapidly. These have provided advantages in vascular imaging. The introduction of dual-source scanners has allowed the possibility of tissue characterization in CT scans. This article briefly discusses the basic principles of MDCT and provides an overview of its application in vascular diseases.
