FIG 2. A, Axial FDG-PET image shows uptake of tracer in the lesion that is difficult to distinguish from cerebral cortex (arrow heads). The region of increased activity, which corresponds to the tumor, is in the left temporal lobe.
B, Axial Met-PET image depicts high uptake of tracer in the lesion. The area of increased accumulation of Met is larger than that of FDG.
