Figure 5
Effect of time and gadolinium dose on ECV. Linear regressions are shown for half-dose and whole-dose Gd epochs. Stress was reversed at 4 min (dotted vertical line); Gd was given at 0 min and a second dose at 19 min (dashed vertical line). The early rapid variation in ECV estimates after Gd seen in the ShMOLLI panel (data points outside the ranges marked by regression models) were excluded from analysis to allow fair inter-method comparisons. ShMOLLI ECV demonstrates little change in ECV with time, whereas MOLLI ECV (particularly MOLLI Low HR) is subject to linear time drift. Confidence intervals for the linear regressions are included (shaded ranges).
