Abstract
At arterial phase gadolinium-enhanced magnetic resonance (MR) angiography, artifactual stenosis of the subclavian artery is sometimes seen adjacent to the subclavian vein on the side of the contrast material injection. Experi ments in phantoms and in 19 patients showed increased artifact with longer echo time and higher concentration of injected contrast material. An effect ive method to substantially decrease this susceptibility artifact was three fold dilution of gadopentetate dimeglumine and use of a short echo time (1 msec).
