The use of duplex sonography permits the study of quantitative hemodynamics in several specific clinical applications, including the study of hemodialysis access grafts, vertebro-basilar insufficiency and iliofemoral atherosclerotic disease. A study was made of a group of 121 patients with nonlocalizing symptoms of cerebrovascular ischemia suggestive of vertebro-basilar disease using quantitative duplex measurements and angiography. In the lower extremities quantitative femoral artery flow measurements have been taken at rest and during periods of reactive hyperemia to determine the significance of iliofemoral lesions. The results of these studies confirm the usefulness of the technique.
