Is CT or MR perfusion better for diagnosing CAD?

By Abraham Kim

Recent advances in scanner technology have made the use of CT stress myocardial perfusion imaging feasible. Just how well it matches up to MR perfusion in the diagnosis of coronary artery disease (CAD) is the central question of a German/U.S. study led by Dr. Marc Dewey from Berlin.
