Hibernating myocardium. a 57-year-old male with coronary artery disease, status post multiple prior percutaneous interventions, with symptoms of angina at rest. Short-axis delayed enhancement MRI shows partial thickness scar in the anterolateral segment (yellow arrow) and near-full thickness scar in inferolateral segment (red arrow). b Rb-82 PET rest perfusion image shows perfusion defect in the anterolateral and inferolateral segments (yellow and red arrows, respectively). This was similar on stress images as well. c FDG-PET image shows no uptake in the inferolateral segment (red arrow) indicating non viability, while there is uptake in the anterolateral segment (yellow arrow), indicating hibernating myocardium
