Absolute stress myocardial blood flow is reduced in patients with prior cardiac disease despite normal perfusion and ejection fraction on rubidium-82 PET: an Arabian Gulf cohort
Purpose Rubidium-82 (⁸2Rb) PET is typically interpreted using perfusion category and left ventricular ejection fraction (LVEF), but absolute myocardial blood flow (MBF) and flow reserve (MFR) may add information. We investigated whether absolute stress MBF differs between patients with and without prior cardiac disease...
