Quantification of absolute myocardial perfusion in patients with coronary artery disease : comparison between cardiovascular magnetic resonance and positron emission tomography

PET was previously the only fully quantitative non-invasive method to measure cardiac perfusion, but is burdened by ionizing radiation, low spatial and temporal resolution, and less accurate detection of myocardial scars. This paper shows for the first time that MR perfusion can be quantified similarly to PET imaging, overcoming one of the last hurdles to MR becoming the method of choice for clinical perfusion imaging. The paper was declared Paper of the Month and Hot Topic by the American Society of Nuclear Cardiology (ASNC) and was published in one of the leading journals for cardiovascular disease.
