FIGURE 2. For dynamic evaluation of [124I]FIAU influx and washout in cats, ROI analysis focused on organs such as brain (1), heart (2), lung (3), muscle (4), liver (5), stomach and spleen (6), kidney (7), intestine (8), and bladder (9). Stomach and intestine could not be differentiated and were combined into one region. Coregistered FDG PET reveals glucose consumption in brain and heart and excretion of tracer into bladder. Coregistered [15O]H2O PET shows high activities in well-perfused organs such as brain, heart, liver, and kidneys.
