Noninvasive techniques have assumed an increasingly important role in the management of patients with vascular disease. Both ultrasonic and plethysmographic instruments allow objective evaluation of vascular disorders by the measurement of segmental limb blood pressures, analysis of blood velocity disturbances, recording of digit or limb pulse waveforms, or imaging of vascular disease, with or without Doppler flow analysis or color-flow mapping. These techniques have been applied for screening asymptomatic individuals, diagnosis of symptomatic patients, monitoring of interventional or surgical procedures, and follow-up of the natural history or the efficacy of medical, interventional, or surgical therapy of vascular disease. This article reviews the clinical application of these modalities to patients with peripheral arterial disease and briefly discusses cost-effectiveness and potential abuses of noninvasive technology.

UI	MeSH Term	Description	Entries
D007383	Intermittent Claudication	A symptom complex characterized by pain and weakness in SKELETAL MUSCLE group associated with exercise, such as leg pain and weakness brought on by walking. Such muscle limpness disappears after a brief rest and is often relates to arterial STENOSIS; muscle ISCHEMIA; and accumulation of LACTATE.	Claudication, Intermittent
D007866	Leg	The inferior part of the lower extremity between the KNEE and the ANKLE.	Legs
D010991	Plethysmography	Recording of change in the size of a part as modified by the circulation in it.	Plethysmographies
D003362	Cost-Benefit Analysis	A method of comparing the cost of a program with its expected benefits in dollars (or other currency). The benefit-to-cost ratio is a measure of total return expected per unit of money spent. This analysis generally excludes consideration of factors that are not measured ultimately in economic terms. In contrast a cost effectiveness in general compares cost with qualitative outcomes.

D001157	Arterial Occlusive Diseases	Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.

D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
