Office Doppler techniques in vascular disease

The Doppler ultrasonic velocity detector is the least expensive and most versatile instrument used to screen patients for peripheral arterial, cerebrovascular, and venous disease. The Doppler detector provides qualitative and quantitative estimates of arterial and venous flow velocity and segmental arterial pressure measurements. The device can become as clinically useful as the stethoscope to screen patients for vascular disorders. New audiovisual instructional aids may make this technique a routine complement to the clinician's diagnostic resources.
