Abstract
Forty patients were examined with intraarterial digital subtraction angiography (DSA) using meglumine iothalamate (202 mg I/ml) or CO2 as a contrast medium. Diagnostic studies were obtained in all patients. The use of CO2 resulted in diagnostic examinations of the common femoral artery to the level of the trifurcation. The use of CO2 and low-I-content contrast material reduced the I dosage, and temporal bandpass filtration DSA permitted a lower entrance exposure than pulsed systems. Intra-arterial DSA, using the techniques described in this paper, apparently will become a more important and widely used procedure than it currently is.
