In this study, we applied a recently developed and robust coronary vessel wall MRI method that includes a golden angle trajectory and k-t sparse SENSE to a cohort of heart transplant patients. The coronary vessel wall was visualized with high contrast in all patients and the method holds great promise for quantitative and non-invasive characterization of coronary allograft vasculopathy (CAV) in transplanted patients.
