Which MRI sequence is used to detect brain edema?
FLAIR stands for Fluid Attenuation Inversion Recovery Sequence This sequence is similar to T2 with suppression of CSF/Fluid signal so the Brain Edema can be seen better. Figure: FLAIR image showing edema in bilateral occipital lobe in a case of PRES(posterior reversible encephalopathy syndrome).
