The assessment of aorto-iliac disease by static isotope angiology.

In 48 patients with severe claudication isotope images of the aortofemoral arteries have been assessed for the severity of disease in 417 anatomical segments and compared with arteriography. An overall correlation of 80 per cent was found; 87 per cent of patent and 76 per cent of occluded segments were correctly identified, but only 68 and 54 per cent of segments with minor and major disease respectively. Underestimation of disease occurred in only 6 per cent.
