[Angiography in arteriosclerosis].
Advances in angiography of arteriosclerosis have been made possible by improvement of angiographic techniques, materials, such as narrow catheters and gliding guidewires, x-ray apparatus and equipments, including digital subtraction angiography (DSA), computed radiography and magnetic resonance angiography and contrast media. Improved, narrow and yet wide lumen catheters have made it possible to insert the catheter via the axillary or brachial artery. The matrix of DSA was increased to 1024 x 1024 from 512 x 512, and resolution of DSA has been greatly improved. Intravenous DSA has made examination of aneurysm or arterial stenosis or occlusion, easier without much harmful invasion. Ionic or non-ionic low osmolar contrast media has greatly reduced the irritation to the vessels.
