Thirty patients with occlusive peripheral vascular disease underwent clinical examination, segmental blood pressure determinations, intra‐arterial digital subtraction angiography, and treadmill stress testing with injection of technetium 99m sestamibi at peak exercise. Radionuclide images of the thighs, calves, and feet showed clear delineation of major muscle groups. Diminished radiotracer distribution was closely correlated with the presence of occlusive vascular disease on angiography and with the presence ofclaudication and reduced segmental blood pressure. A quantitative scheme based on pixel intensity was developed to compare areas of regional perfusion.
