Peripheral arterial disease (PAD) represents a growing public health issue that continues to be underdiagnosed. In its most severe form, critical limb ischemia, it contributes to expanding morbidity with minor and major limb amputations. PAD is strongly associated with increased mortality, as it is known to be concomitant with coronary and cerebrovascular disease. Diagnosis of PAD relies on noninvasive arterial testing, a class of tests that can provide physiologic or morphologic information. Physiologic tests such as ankle-brachial index, toe-brachial index, pulse volume recordings, and arterial duplex evaluation are the mainstay of gateway evaluation and surveillance. Morphologic exams such as computer tomographic angiography and magnetic resonance angiography are appropriate for preprocedural anatomic evaluation in patients with established vascular disease. This review focuses on physiologic exams.
