  • Title: Peripheral vascular disease: prospective study of intraarterial digital subtraction angiography using a 9-inch intensifier.
    Author: Garvey CJ, Wilkins RA, Lewis JD.
    Journal: Radiology; 1986 May; 159(2):423-7. PubMed ID: 3515419.
    Abstract:
    A prospective randomized study was undertaken to evaluate the role of intraarterial digital subtraction angiography (IADSA) in the study of peripheral vascular disease. Patients underwent either conventional film-based angiography alone, digital subtraction angiography (DSA) alone, or a combined study. With a 9-inch image intensifier, DSA alone resulted in cost savings of film and contrast material but required a significantly longer examination period than the other groups and an increased iodine dose per examination. When the images were analyzed by a radiologist and a vascular surgeon, the DSA studies provided less detail in the aortoiliac region than the other techniques but had advantages in demonstrating the runoff vessels. IADSA examination should not replace conventional arteriography in patients with peripheral vascular disease but has a useful complementary role.
