[Abstract] T2-fluid attenuated inversion recovery (FLAIR) mismatch sign is an easily recognized imaging sign in conventional magnetic resonance imaging, which is characterized by homogenous hyperintensity of the glioma on T2WI and can be suppressed by FLAIR. A large number of studies have shown that this sign can effectively predict the molecular typing of lower–grade gliomas, especially for the prediction of isocitrate dehydrogenase (IDH) mutation and 1p/19q non-codeletion. T2-FLAIR mismatch sign has great potential in future clinical application due to its noninvasive and high specificity. In this paper, we review the definition of T2-FLAIR mismatch sign, pathological-image mechanism, and clinical application.
