[ 3 ] - Methods to Improve Fiber Reconstruction at DTI-Based Tractography in the Area of Brain Tumor: Case Illustration and Literature Review
Background and Aim: DTI-based tractography could help us to visualize the spatial relation of fiber tracts to brain lesions. Several factors may interfere with the procedure of diffusion-based tractography, especially in brain tumors. The aim of the current study is to discuss several solutions to improve the procedure of fiber reconstruction adjacent or inside brain lesions. Illustrative cases...
[ 4 ] - Application of 5-ALA Fluorescence-Guided Resection in Patients Suffering from High-Grade Gliomas: Report of 30 Consecutive Cases and a Literature Review
Background and Importance: The extent of resection seems a solid prognostic factor in patients suffering from high-grade gliomas (HGGs). When administered orally, 5-ALA is exclusively converted by malignant cells into protoporphyrin IX (PPIX), identifying contrast-enhancing glial lesions under blue 400-nm light. The authors thoroughly assess the efficacy, accuracy, and safety profile of 5-ALA-g...
