Acceleration Apportionment: A Method of Improved 2D SENSE Acceleration Applied to 3D Contrast-Enhanced MR Angiography

摘要

PurposeIn 2D SENSE-accelerated 3D Cartesian acquisition, the net acceleration factor R is the product of the two individual accelerations, R = RY × RZ. Acceleration Apportionment tailors acceleration parameters (RY, RZ) to improve parallel imaging performance on a patient- and coil-specific basis and is demonstrated in contrast-enhanced MR angiography.
