Highly accelerated TWIST MRA with standard and iterative reconstruction was compared to a standard TWIST technique in 11 patients with AVM of the hand and/or fingers. Qualitative and quantitative analysis revealed significant advantages for the accelerated protocol with iterative reconstruction: Separation of arterial and venous phase as well as delineation of central and peripheral arterial feeders were significantly improved due to higher temporal resolution compared with our standard protocol while maintaining high spatial resolution.
