Representative case of cardiac sarcoidosis Maximum intensity projection (MIP) image of ¹⁸F-FDG PET (A), PET/CT coronal image (B), short-axis image of ¹⁸F-FDG PET (C), late gadolinium enhancement (LGE)-MRI (D), and fused image of ¹⁸F-FDG PET and LGE-MRI (E) at pre-therapy, MIP image of ¹⁸F-FDG PET (F) and PET/CT coronal image (G) at post-therapy (steroid 30 mg/1 month) are displayed. ¹⁸F-FDG PET detected focal cardiac uptake and multiple lymph node disease in the supraclavicular, mediastinum, hilum, abdominal, and pelvis region at pre-therapy. ¹⁸F-FDG uptake is seen at the same site of LGE-MRI abnormal intensity. At post-therapy, ¹⁸F-FDG uptakes were markedly lower. ¹⁸F-FDG is useful not only for diagnosis but also to confirm the effectiveness of treatments
