Quantitative assessment of cardiac function requires 3D cardiac cine MRI with retrospective gating. Recently developed kt methods have shown potential for highly accelerated cine MRI. However, limited work has been done to address retrospective gating, especially with 3D cine imaging. This work develops a kat ARC-based fast dynamic imaging method for retrospectively-gated 3D cine MRI. Based on our evaluations on 4 volunteers, the proposed method can achieve 8x acceleration using 8-channel cardiac coils and provide high-quality motion depiction of the entire ventricle in a single breathhold.
