Estimates of D (a–c) and F (d–f) in parametric maps derived from LS (triangle) and BLN (circle) error models were measured in multiple ROI’s colocalized across four gating variants (a, b, d, e) in the left (a, d) and right lobes (b, e) of the liver. The ungated left and right lobe estimates are shown in (c, f). Median and 25–75% quantiles are shown. P-values are shown for the hypothesis that BLN estimates changed less than LS estimates as a function of gating or lobe. P-values annotated with (#) support the opposite hypothesis. Gating- and lobe-dependent changes in D and lobe-dependent changes in F were significantly lower for BLN estimates than for LS estimates (P<0.05).
