The T2-FLAIR mismatch sign as an imaging marker for non-enhancing IDH-mutant, lp/19q-intact lower-grade glioma: a validation study

摘要

Background. The purpose of this study was to assess the reproducibility of the previously described T2-fluid attenuated inversion recovery (FLAIR) mismatch sign as a specific imaging marker in non-enhancing isocitrate dehydrogenase (IDH) mutant, 1p/19q non-codeleted lower-grade glioma (LGG), encompassing both diffuse and anaplastic astrocytoma.
