Brain Tumor Case 01
MRI FINDINGS: The contrast-enhanced MRI image (left image) showed an area of contrast accumulation near the surgical region (white arrow), which suggested possible tumor recurrence.
NUCLEAR MEDICINE PET
PET FINDINGS: The PET scan (right image) showed there was no corresponding radiopharmaceutical uptake in the region of contrast accumulation seen on the MRI scan. These results suggested that the contrast enhancement observed in the MR image was the result of radiation necrosis and that no residual tumor was present at that time.
