Noninvasive Testing in Peripheral Arterial Disease

Abstract

Most patients suspected of having peripheral arterial disease should undergo noninvasive vascular testing to confirm the diagnosis, and to determine the severity and extent of the disease. This article reviews practical aspects of commonly used noninvasive tests for lower extremity peripheral arterial disease, including the ankle-brachial index, segmental limb pressures, pulse volume recordings, duplex ultrasonography, computed tomography angiography, and magnetic resonance angiography.
