We present the combination of ECG-triggered retrospective gating and compressed sensing for segmented 2D Cine imaging at high spatiotemporal resolution. This enables capturing the complete cardiac cycle in segmented acquisitions, while significantly reducing the total acquisition time with compressed sensing and auto-calibration. The method was evaluated in 8 healthy volunteers and ventricular function parameters were compared to reference 2D Cine acquisitions featuring ECG-triggered retro-gating. Both methods resulted in comparable image quality and equivalent quantitative values for ventricular function parameters.
