We present the evaluation results of a new motion correction algorithm, designed specifically to account for the variable image contrast found in T1 mapping MOLLI series.

While standard motion correction improves mapping accuracy with respect to uncorrected series, the registration can occasionally diverge, aggravating the problem. The new dedicated algorithm has been shown to yield improved registration performance and reduced probability of divergence.
