The performance of 3D SENSE accelerated CE-MRA can be improved by intelligently apportioning the acceleration between the two phase encode directions. The field of view, anatomy to be imaged, and receive coil array positioning may support an optimal set of accelerations that provides maximum acceleration with minimum penalty. We provide framework for finding this optimal set of accelerations, and demonstrate in-vivo a 20% increase in acceleration with negligible increase in g-factor based noise amplification.
