IR — STIR · 3T

TR = 4000 ms · TI = 220 ms (fat null at 3T — longer T1=380ms) · TE = 60 ms · 3 cycles — TI must increase vs 1.5T because fat T1 is longer at 3T

Fat (T1=380ms at 3T) — nulled at TI=220ms

White matter (T1=830ms at 3T)

Grey matter (T1=1300ms at 3T)

Muscle (T1=1412ms at 3T)

CSF (T1=4000ms at 3T)
