Magnetic resonance stress imaging of myocardial perfusion and wall motion.

Cardiac magnetic resonance (CMR) imaging is a powerful tool for the detection and management of coronary artery disease. Beyond morphology, CMR imaging can probe relevant physiological parameters such as perfusion and function by means of stress testing. This article reviews current applications of CMR stress imaging with an emphasis upon vasodilators and positive inotropic agents. Further, technical aspects, image interpretation, diagnostic performance, and prognostic value of stress tests will be addressed.
