Cardiac magnetic resonance is the gold standard for left ventricular (LV) function assessment; however, current clinical protocols follow a rather complex workflow to plan and to acquire standard short-axis cine MR images. To simplify the workflow and remove these hurdles, we implemented and validated a time efficient free-running, free-breathing, fully self-gated cardiac and respiratory motion-resolved 5D MRI framework with isotropic spatial resolution. Assessment of LV function using the proposed framework and conventional 2D cines demonstrated good agreement between both techniques. When compared to the conventional approach, the proposed framework improves time efficiency and facilitates workflow.
