FIGURE 5. Quantitative kinetics of [124I]FIAU in plasma, scalp, tumor, paratumoral area, gray matter, and white matter of 50-y-old male patient with recurrent glioblastoma. Maximum values are reached in tumor and scalp regions within 5–10 min after injection. FIAU washout from tumor and scalp follows similar kinetics. Gray and white matter [124I]FIAU uptake values are always much lower than those in tumor. Symbols represent PET frames acquired sequentially. For clarity in graph, symbols for first 11 frames acquired during first hour after [124I]FIAU injection are omitted. Curves are model fits to data.
