Popis:	Myocardial tissue characterization by MR TTo develop a robust motion correction method for TRetrospective analysis of clinical data.Fifty patients who were referred to cardiac MR exam for T3.0T cardiac MRI with precontrast and postcontrast MOLLI acquisition of the left ventricle (LV).A groupwise registration method based on principle component analysis (PCA) was developed to register all MOLLI frames simultaneously. The resulting TPaired variables were compared using the Wilcoxon signed-rank test.The groupwise registration method demonstrated improved registration performance compared to pairwise registration, with the TWe developed an automatic, robust motion correction method for myocardial T3 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2018;47:1397-1405.
