Velocity encoded MRI has clinical significance in the diagnosis of coronary artery disease. High spatial and temporal resolution increase the accuracy and reproducibility and preserve reliable flow pattern. By using rotated golden angle with k-t space reconstruction and retrospective cardiac gating, high quality flow CINE could be achieved with high spatial and temporal resolution during a single breath-hold. However, binning to cardiac frames may lead to large gaps in k-space. In this work, we propose a new scheme of rotated golden angle and optimized retrospective gating by shifting the binning window. Improved image quality is demonstrated with the proposed methods.
