Abstract

During an 18 month period 39 patients were evaluated with [F-18] fluorodeoxyglucose-PET (FDG-PET) for primary brain tumours. These includedpatients with suspected newly diagnosed tumours and patients with known tumours who were being evaluated for possible recurrence or increasing tumour grade. Scans were performed on a 951-31 Siemen's PET scanner with 4 mm resolution. Scanning time was about 20 minutes per patient. Ah patients had undergone recent cerebral MRI. These patients were divided into two groups. In the first group (30) MRI and PET concurred on the diagnosis. The second group (nine) comprised those where the interpretation of MRI and PET was different or there was a question of the diagnosis on MRI. This group comprised three patients in whom MRI suggested recurrent tumour and PET inaccurately suggested radiation necrosis; two patients with newly diagnosed enhancing lesions on MRI in whom PET was useful in distinguishing strokes from tumour; two patientswith prior gliomas with new enhancing isolated lesions on MRI in whomPET scan accurately depicted radiation necrosis; and two patients with newly diagnosed enhancing lesions on MRI in whom PET scan was helpful in distinguishing multiple sclerosis from tumour in one but not in the other. Therefore, of the 39 patients, PET was helpful in five in distinguishing tumour from other disease processes; but, in so far as influencing treatment, it seemed helpful in only two. Thus PET seems to be of limited value as an aid to evaluating and treating patients withsuspected or known primary brain tumours.
