Fig. 2From: The clinical significance of the T2-FLAIR mismatch sign in grade II and III gliomas: a population-based studya-b: a) FLAIR sequence demonstrating a relative hypointense signal with the exception of a hyperintense peripheral rim. b) T2W sequence demonstrating homogenous hyperintensive signal with a conspicuous border. This glioma was considered to have a mismatch sign and was diagnosed with an IDH-mutated and 1p19q codeleted glioma (i.e. oligodendroglioma)Back to article page
