Which MRI sequence is used to detect brain edema?
T1WI
FLAIR
SWI
DWI
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).
