We investigate the diagnostic performance of native T1 and T2 mapping cardiovascular magnetic resonance imaging (CMR) for cardiac allograft vasculopathy (CAV) after heart transplantation, using myocardial flow reserve (MFR) estimated by 13N-ammonia (NH3) positron emission tomography (PET) as reference. Non-contrast native T1 mapping is a minimally invasive and effective method for monitoring CAV. In contrast, the effectiveness of T2 mapping could not be demonstrated.
