Myocardial infarction. a Short-axis delayed enhancement MRI in a patient with myocardial infarction shows a large transmural scar of the anterior wall (yellow arrow) and partial thickness scarring of the inferolateral segment (red arrow). Viability of this segment is borderline. b Fused PET/MR image shows no uptake in the anterior as well as inferolateral segments, indicating that these are not viable. Thus, the combination of these imaging modalities improves the diagnostic confidence
