The combination of keyhole, CENTRA, parallel imaging, partial Fourier, and view-sharing allows for high spatial and sub-second temporal resolution 4D MRA with whole head coverage. 4DMRA was evaluated in the entire diagnostic work-up of patients with cerebral arteriovenous malformations (cAVM) including pre- and post-operative assessment and was compared to digital subtraction angiography (DSA) in 38 consecutive patients. Highly accelerated 4DMRA matched with DSA in all patients regarding pre-operative Spetzler-Martin Classification and post-operative residual filling and may be considered a non-invasive alternative in the diagnostic work-up of patients with cAVM.
