Article
BACKGROUND The first-line treatment for high-grade gliomas (HGG) is maximal safe resection, which is limited by diffuse tumor margins and nearby eloquent areas. Intraoperative detection of tumor cells is improved with fluorescence-guided surgery using 5-ALA, but its visual detection is limited by blood, obstacles and weakness of the fluorescence. A...
Article
Background : 5-aminolevulinic acid (5-ALA) – precursor of protoporphyrin IX (PpIX) – is utilized in fluorescence guided surgery (FGS) of high-grade gliomas. PpIX is used to identify traces of glioma during resection. Visual inspection of the fluorescence seems inaccurate in comparison to optic techniques such as hyperspectral imaging (HSI). Aim :...
