A quantitative metric of cardiac alignment has been defined and validated. Using this metric, a dedicated motion correction for MOLLI series has been tested on a large clinical database, showing a noticeable increase in robustness.

Figure 2.- Scatter plot of the improvement in the anatomical alignment metric, obtained with each of the motion correction methods, with respect to uncorrected data. Each data sample corresponds to one 2D MOLLI series.
