Differentiating low‐ and high‐grade pediatric brain tumors using a continuous‐time random‐walk diffusion model at high <i>b</i>‐values

Abstract

With its sensitivity to intravoxel heterogeneity, the simplified CTRW model is useful for non-invasive grading of pediatric brain tumors, particularly when surgical biopsy is not feasible. Magn Reson Med 76:1149-1157, 2016. © 2015 Wiley Periodicals, Inc.
