Abstract: The presence of subendocardial dark‐rim artifact (DRA) remains an ongoing challenge in first‐pass perfusion (FPP) cardiac magnetic resonance imaging (MRI). We propose a free‐breathing FPP imaging scheme with Cartesian sampling that is optimized to minimize… read more here.

Abstract: Optimizing three‐dimensional (3D) k‐space sampling trajectories is important for efficient MRI yet presents a challenging computational problem. This work proposes a generalized framework for optimizing 3D non‐Cartesian sampling patterns via data‐driven optimization. read more here.
