Abstract excerpt

PURPOSE: To test whether a refined definition of the T2-FLAIR mismatch sign (redefined T2FM) and a newly defined subcortical FLAIR signal drop (scFLAIR-D) on conventional MRI improve presurgical discrimination between astrocytoma, IDH-mutant (AST) and oligodendroglioma, IDH-mutant and 1p/19q-codeleted (ODG). MATERIALS AND METHODS: In this single-center retrospective study (January 2021-July 2025), adults with...
