In this study, left ventricular tissue relaxometry and dynamics measurements (T 2 mapping and slice-followed CSPAMM myocardial tagging) were combined to longitudinally and quantitatively characterize the myocardium of heart transplant recipients in comparison to the gold standard myocardial biopsy. Initial results obtained in a small patient cohort are presented and discussed.
