The assessment of myocardial perfusion has shown to provide high diagnostic and prognostic information for the management of patients with CAD. Quantification of perfusion remains a challenge for the regional measurement of myocardial flow reserve by a variety of imaging techniques. Newly developed integrated PET/MR devices are uniquely suited to compare perfusion measurements in patients. Here we describe a protocol for parallel acquisitions of myocardial perfusion by PET and MR, and the direct comparison of simultaneous measurements of myocardial perfusion at rest and during pharmacologic stress.
