Occult infarction presages major event

January 1, 2009 Diagnostic Imaging. Vol. 31 No. 1 Occult infarction presages major event Enhanced MR protocol helps stratify patients By James Brice Dr. Stephan Miller and colleagues at the University of Tübingen in Germany have discovered that silent myocardial infarction raises the likelihood of a future major cardiac event for 14% of patients with symptomatic peripheral vascular disease evaluated with MRA. They made the finding after developing a new MR protocol that combined delayedenhancement myocardial MRA with a conventional contrast-enhanced peripheral vascular runoff study. The delayed myocardial perfusion images were acquired 10 minutes after MRA using the same 0.18-mmol administration of gadolinium-based contrast media.
