We assessed clinical utilities of an ASL-based
non-contrast 4D MRA (inflow enhanced inversion recovery
(IFIR) 4D MRA) incorporated into routine MRI protocols
for patients with cerebral arteriovenous malformation
(AVM). Non-contrast IFIR 4D MRA has a high spatial
resolution almost equivalent to that of 3D TOF MRA and
also can provide a higher temporal resolution than
contrast-enhanced time-resolved MRA. Non-contrast IFIR
4D MRA was found to add hemodynamic information to 3D
TOF MRA and can be an alternative to contrast-enhanced
time-resolved MRA in evaluation of cerebral AVM.
