Objective: Gadolinium enhanced MR imaging has been shown to be of limited value in differentiating brain tumor recurrence from pseudoprogression due to therapeutic effects of irradiation and chemotherapy. Metabolic imaging (FET-PET) is an accepted but not ubiquitously available modality for differentiation.[for full text, please go to the a.m. URL]
