Comparative Study Clinical TrialComparison of (18)F-FET PET and 5-ALA fluorescence in cerebral gliomas.
The aim of the study was to compare presurgical (18)F-fluoroethyl-L: -tyrosine ((18)F-FET) uptake and Gd-diethylenetriaminepentaacetic acid (DTPA) enhancement on MRI (Gd) with intraoperative 5-aminolevulinic acid (5-ALA) fluorescence in cerebral gliomas. ⋯ There are differences between (18)F-FET and 5-ALA uptake in cerebral gliomas owing to a limited sensitivity of 5-ALA to detect tumour tissue especially in LGG. (18)F-FET PET is more sensitive to detect glioma tissue than 5-ALA fluorescence and should be considered as an additional tool in resection planning.
