Fluorescence Spectroscopy Guided Surgery

A prototype of intraoperative fluorescence spectroscope will be used for fluorescence spectroscopy during a surgical procedure (open surgical approach only). The experimental probe dedicated to the spectroscopic system will be positioned against the surface of the brain, emission spectrum will be acquired and measured, and finally compared with anatomopathology exams. One specific medication will be used as contrast agent in the study: 5 amino-levulinic hydrochloride (GLIOLAN, MEDAC) orally at the dose of 20mg/kg of body weight.
