Cartesian Acquisition with PR-Like Sampling (CAPR)

Purpose: To combine 2D acceleration from SENSE and homodyne with view sharing to enable time-resolved 3D CE-MRA with isotropic spatial resolution and crisp temporal dynamics for characterization of transient signals. For this a CArtesian Projection-Reconstruction-like (CAPR) acquisition is used. CAPR differs from other accelerated imaging sequences because of the high level of centricity, the temporal compactness of the center of k-space, and the short temporal footprint. It is the goal of this work to describe the technique and show high diagnostic quality images from CAPR sequences adapted to peripheral vascul…
