The major challenge neurosurgeons encounter when resecting infiltrative gliomas is the identification of the glioma tumor margin to perform a radical [[resection]] while avoiding and preserving [[eloquent]] [[region]]s of the brain. [[5-aminolevulinic acid]] (5-ALA) remains the only optical-imaging agent approved by the [[FDA]] for use in [[glioma surgery]] and the identification of [[tumor]] [[tissue]]

[[5-ALA]]-based [[fluorescence guided surgery]] has been shown to be a safe and effective method to improve intraoperative visualization and resection of [[malignant glioma]]s. However, it remains ineffective in guiding the resection of lower-grade, non-enhancing, and deep-seated tumors, mainly because these tumors do not produce detectable fluorescence with conventional visualization technologies, namely, wide-field (WF) [[surgical microscope]].
The introduction of [[fluorescence guided resection]] (FGS) represents one of the most important advances in the neurosurgical treatment of brain tumors.

[[5-aminolevulinic acid ]] [[fluorescence guided resection]] permits the intraoperative visualization of [[malignant glioma]] tissue and supports the neurosurgeon with real-time guidance for differentiating tumor from normal brain that is independent of [[neuronavigation]] and [[brain shift]].
