Interventional fluorescence spectroscopy: preliminary results to detect tumor margins during glioma resection with two fluorescence spectra of PpIX

摘要

We show the feasibility of using an intraoperative spectroscopic device to identify tumors margins during glioma resection. The collected fluorescence spectra is fitted with two reference spectra of PplX and the contribution of each spectrum enables to overcome the sensitivity of current techniques by seeing tumor margins and low grade gliomas.
