Evaluation of cardiac infiltration. a FDG PET/CT in a patient with lymphoma shows a focus of hypermetabolism adjacent to the SVC. The exact extent of this is not evident in the PET or the concomitant low-dose CT scan. b MRI was performed for evaluating cardiac extension. T1-weighted axial image shows that the mass (thin arrow) has a clear fat plane (thick arrow) with the SVC and cardiac structures, indicating that it is not infiltrating the cardiac structures
