Objective: PET using 18F FET (fluoroethyl-L-tyrosine) and 18F-FDG (fluoro- desoxyglucose) are widely used for non-invasive preoperative grading of glial brain tumors. However, the correlation of FDG and amino acid PET uptake with histological grade in pure oligodendrogliomas is discussed controversially.[for full text, please go to the a.m. URL]
