Purpose High temporal and spatial resolutions are required for coronary blood flow measures. Current spiral breath‐hold phase contrast (PC) MRI at 3T focus on either high spatial or high temporal resolution. We propose a golden angle (GA) rotated Spiral k‐t Sparse Parallel imaging (GASSP) sequence f...
