ABSTRACT
Though intravenous digital subtraction angiography (IV DSA) has several advantages over conventionalangiography in diagnosis and follow up of various vascular disease, it also has several undesirable problems suchas large volume of the contrast medium and inferior image quality compared to conventional angiography. Sorecently intraarterial digital subtraction angiography (IA DSA) was introduced for better image quality usingsmall amount of contrast medium. The authours had good clinical results IA DSA which were made in 20 patients withour own system, SRM-II, developed by cooperation of Departements of Radiology and Medical engineering, Seoul.National University Hospital. Intraarterial digital substraction angiography was found to have several advantagesover conventional angiography (a) small amount of contrast medium, (b) reduced need for selective arterialcatheterization,(c) lower film cost, (d) shortened examination time, (e) ability to obtain a “road map”, and (f)easier detection of contrast medium. Also IA DSA has several advantages over IV DSA (a) less dependency oncardiac output, (b) far less vessel overlapping, (c) reduction in patient motion through less painful procedure byreduced volume of contrast media and shorter imaging time.
