Figure 2

Left: 3D visualization of two tumors (T2 and T3) using parametric imaging with three basis functions: stable (blue), decreasing (green), and increasing (red) represented in the left corner of each image (the number of chemotherapy courses between each PET exam is mentioned). Parametric imaging using 2 (A), 3 (B), 4 (C), and 5 (D) exams. Right: SUVmean evolution (calculated within a ROI defined by 40% of SUVmax) for the two tumors. Note that the non-responding T2 tumor was detected with parametric imaging earlier (exam 2) than applying EORTC criteria that concluded to a stable disease between exam 2 and 3.
