Saturation recovery sampling strategies considered in protocol comparisons: (a) uniformly distributed saturation delays, (b) fixed saturation delay, (c) uniformly distributed saturation delays plus added recovery beats, and (d) brute force optimization of sampling. All schemes acquired an initial non-saturated “anchor” image (plotted at 9500 ms) and all protocol comparisons had equal duration acquisitions (RR = 1000 ms in this illustration).
