Quantitative perfusion reserve of 1.5 and 3 Tesla cardiac magnetic resonance imaging was compared against the angiographic standard of fractional flow reserve. 34 patients underwent imaging at both field strengths including adenosine-perfusion, and within 72 hours invasive coronary angiography including fractional flow reserve in all major coronary arteries. Our results suggest 3 Tesla perfusion imaging to be superior to 1.5 Tesla for the detection of significant coronary artery stenosis.
