  1. *Considering the tolerance of most individuals, a maximum breath-hold duration of 12 s was selected, leading to some acquisitions being split over two breathholds for some cases.
  2. *The GRAPPA factor is a parameter used in parallel imaging techniques for accelerating MRI acquisition, which represents the level of under-sampling in k-space.
  3. GRAPPA = GeneRalized Autocalibrating Partially Parallel Acquisition; FOV = field-of-view; LAX = long-axis; SAX = short-axis; TE = echo time; TR = repetition time.
