a–e Coronal [¹⁸F]-FDG-PET slices with different intensity levels (a, b) show the relation between radiotracer accumulation in the bladder (SUVmax 12,8) and both involved kidneys (SUVmax right: 38,02; SUVmax left: 42,91). Coronal fusion images display multiple, metabolically active lesions in both kidneys (c). On coronal MR T2-TIRM images both kidneys are enlarged and corticomedullary junctions are blurred (d). Multiple foci in both kidneys are almost restricted in diffusion (ADC about 908 × 10–6 mm2/s) (e)
