MRI Sequences Decoded MRI sequences can be tricky, but here's a quick breakdown with mnemonics to make them stick! T1-weighted -> "T1: White is White, Gray is Gray" > White matter = lighter, gray matter = darker, CSF = black, fat = white -> Best for anatomy & structural details. ◦ T2-weighted -> "T2: H20 is White" ○ Fluid (CSF) = white, fat = white, white matter = darker, gray matter = lighter -> Best for pathology (edema, inflammation, tumors, infection). > FLAIR -> "FLAIR Clears CSF" CSF suppr
