Intraaxial tumors of the central lobe are challenging lesions to deal with because of the high eloquence of this anatomic area. 1,2 Diffusion tensor imaging magnetic resonance imaging and fluorescein (F) have proven to be useful in the planning and execution, respectively of glioma surgery. 3-9 Nevertheless, the advantages of intraoperative use of augmented reality (AR) with diffusion tensor imaging−based high-definition fiber tractography (HDFT) are still underestimated. In the AR HDFT-F technique reported by our group, the integration of AR into the microscope comes through the BrainLAB Curve navigation platform (BrainLAB AG, Munich Germany), Smartbrush software (BrainLAB AG), KINEVO 900 surgical microscope (Carl Zeiss, Oberkochen, Germany), and YELLOW 560 filter (Carl Zeiss). 9 The microscope establishes a wired autodetection of the navigation platform, and the eyepiece functions as a "see-through display" of the AR images, which are overlapped onto the surgical field. Video 1 shows the technical key aspects of the intraoperative use of the AR HDFT-F technique in the maximal safe anatomic resection of a postcentral gyrus high-grade glioma. [ABSTRACT FROM AUTHOR]
