T2 flare frontal lobe meaning
WebFluid-attenuated inversion recovery (FLAIR) is an MRI technique that shows areas of tissue T2 prolongation as bright while suppressing (darkening) cerebrospinal fluid (CSF) signal, thus clearly revealing lesions in proximity to CSF, such as cerebral cortical lesions. 19-21 FLAIR was initially limited by a long acquisition time, but now it can ... WebDemyelination typically progresses from the parietooccipital to frontotemporal lobes and involves the corpus callosum from posterior to anterior. Affected regions appear hyperintense on T2-weighted FLAIR images and hypointense on T1-weighted images with variable enhancement (Figs. 7A and 7B). In certain cases, lesions may calcify or produce ...
