Recently 3D volumetric non contrast time-resolved MRA
technique termed Contrast inherent inflow enhanced multi
phase angiography combining multiple phase FAIR
(CINEMA-FAIR) was proposed. CINEMA technique combines
ASL with 3D segmented T1 weighted gradient echo
sequence. FAIR preparation scheme with the Look-Locker
sampling was used for spin tagging in this study. This
study assessed the utility of CINEMA-FAIR as a
diagnostic tool for intracranial AVF and AVM compared
with contrast-enhanced dynamic MR angiography (CE-dMRA).
CINEMA-FAIR could show comparable result from many view
points, but was inferior to CE-dMRA in depicting
drainage vein of AVM.
