Keywords: Myocardium, Quantitative ImagingApproximate myocardial spin-lock (SL) dispersion mapping was obtained using simultaneous TRAFF2 and T2 mapping with good image quality and consistent repeatability among healthy subjects at 3T. Initial patient data indicates clinical feasibility and sensitivity to scar tissue, as identified by LGE. T2 and TRAFF2 are sensitive to distinct macromolecular interactions, showing differential contrast in disease. SL dispersion may exploit this and allow for isolating contrast components (e.g. chemical exchange effects). Our results suggest that these may allow for robust, complementary, and comprehensive clinical sensitivity to pathological remodeling. Future evaluation in a larger patient cohort with different myocardial injuries is warranted.
