A: PET scan shows accumulation of FDG in left renal tumor (green asteroid, SUVmax: 14.5), liver (yellow arrows, SUVmax: 7.1), lung (not shown, SUVmax: 3.7), and Th3 vertebra (yellow arrowhead, SUVmax: 8.8). In this case, the highest SUVmax of the metastatic tumors (m-SUVmax) is 8.8. Blue circle shows left pleural effusion. B: Chest CT shows a tumor in left lung (blue arrow) and pleural effusion (blue circle).
