Cardiac MRI demonstrates differences between heart transplant recipients more than one year post-HTx and controls using T2, T1 and ECV. Our study demonstrated elevated global T2 and ECV, and segmental T1 in HTx patients when compared to controls. This may provide further insight into the complex pathophysiology of this disease process, which includes a chronic and subacute component. CMR could potentially be implemented as an adjunct to the current methods of detecting CAV (intravascular ultrasound and invasive coronary cineangiography)
