Comparison of prior breath-hold Cartesian (A & B), free-breathing GRASP (C & D), and free-breathing XD-GRASP (E & F) studies in a 40 year old female patient undergoing post-liver-transplant surveillance. The left column shows early-arterial-phase acquisitions, and the right column shows late-arterial-phase acquisitions. For the Cartesian study, both early (A) and late (B) arterial phase acquisitions were performed in a single breath-hold. A subsequent exam was performed in the same patient with free-breathing radial acquisition during contrast injection. Early and late phase arterial phases of enhancement were reconstructed from the same raw data using GRASP (C & D) and XD-GRASP (E & F). XD-GRASP reconstructions received higher scores of image quality from both readers compared to GRASP and BH exam.
