¹⁸F-FDG PET/CT in cardiac sarcoidosis. (A) Representative transaxial CT, PET, and PET/CT fusion images of cardiac region (left) showing strongly increased septal uptake consistent with biopsy-proven active cardiac sarcoidosis. Images of lung region (right), along with whole-body maximum-intensity projection (MIP), show mild, diffuse uptake in both lung lobes indicating moderately active pulmonary sarcoidosis. (B) Integration with cardiac MRI (CMR), showing transmural late gadolinium enhancement in anterior wall, septum, and anterior portion of right ventricle, colocalizing with ¹⁸F-FDG uptake in reangulated short-axis PET/CT images.
