CMR feature-tracking derived strain measurements from a 16-fold
accelerated, real-time cine had good agreement with measurements derived from
standard breath-hold cine. But, there can be underestimation which is dependent
on spatiotemporal resolution and CS regularization weights.

2: Comparison of CMR-FT derived radial and circumferential strain maps during peak
systole for the standard cine and real-time cine at the basal slice, mid-slice
and apical slice. Note that in the real-time cine, images have larger
tracking-windows when compared to the corresponding standard cine images.
