Certain doppler procedures can be used as screening methods, and may be helpful in detecting and locating arterial occlusive disease in the patient with vertebrogenic sciatica or claudication syndromes of the lower extremities. The doppler has become popular in the office setting because it is quick, noninvasive and inexpensive. The procedures can be performed even with the simple stethoscope doppler.
