A Comparison of Radio-Pathomic, Diffusion, and Perfusion Imaging Features for Identifying Pseudoprogression in Glioblastoma.
INTRODUCTION Glioblastoma is an aggressive brain tumor with poor survival rates and nearly universal recurrence. Magnetic resonance (MR) imaging obtained after radiation and chemotherapy treatment often shows "pseudoprogression" (PsP), or contrast enhancement that mimics tumor growth. However, this does not indicate ac...
