Two cases of postsurgical brain tumor evaluation in which MRI was inconclusive are discussed. Functional imaging techniques, such as FDG-PET and {sup 201}TI SPECT, were used in both cases for distinguishing radiation necrosis from tumor recurrence. These methods proved to be complimentary. For Patient 1, FDG-PET showed more limitations compared to {sup 201}Tl SPECT. FDG-PET results, on the other hand, were consistent with the final diagnosis and the SPECT image was false positive for tumor recurrence in Patient 2. 26 refs., 9 figs.
