Perfusion Cardiac MRI Determines Severity of Coronary Artery Stenosis

A new technique for measuring blood perfusion reserve with cardiac magnetic resonance imaging (MRI) improves the evaluation of three-vessel coronary artery disease and identifies scarred myocardium supplied by a severely narrowed artery. Cardiac MRI is a “very comprehensive exam” that provides information that other imaging modalities can’t, senior author Dr. Christopher M. Kramer from the University of Virginia, Charlottesville, told Reuters Health.
