Measurement of Absolute Epicardial Coronary Artery Flow and Flow Reserve With Breath-Hold Cine Phase-Contrast Magnetic Resonance Imaging

Abstract

MRI measurements of coronary flow and flow reserve were in good agreement with US measurements. In addition, MRI measurements of coronary flow reserve successfully discriminated stenotic from normal vessels. These results indicate that MRI is a useful method for the noninvasive assessment of coronary flow and stenosis.
