Intra-arterial digital subtraction angiography
Computed radiography (CR) produces an image with frequency enhancement and a digital subtraction angiogram (DSA) as well as an image similar to that obtained with the conventional screen/film system. CR is thus recognized as a new system which can deal with many angiograms. This chapter presents clinical cases of intra-arterial DSA using CR and the advantages and problems of this system are discussed.
