A 48-year-old man, a known case of Friedreich's ataxia (FRDA) underwent cardiac fluorodeoxyglucose (FDG) positron emission tomography -computed tomography (PET/CT) for evaluation of myocardial viability. Tetrofosmin images showed an enlarged left ventricular cavity with small mid and basal inferior and apical infarct global hypokinesia with ejection fraction of 39%.
