[Comparison of intra-arterial digital subtraction angiography with conventional arteriography].

Conventional arteriography and intra-arterial DSA were compared in 243 individuals for examination of the liver, kidney, lower extremity and portal vein. There was no significant difference in the diagnostic value of these methods. DSA suffers from a poorer spatial resolution in the periphery of vessels, but this has not resulted in a loss of clinically relevant information.
