Cardiac MRF (cMRF) has recently emerged as a method of rapidly characterizing
myocardial tissue. It has been shown to be robust to different and varying heart rates with
high reproducibility in T 1 and T 2 regardless of the length and regularity of the cardiac cycle.
While these techniques have been validated in healthy volunteers, patient studies have yet
to be performed. Therefore, in this abstract, we present the first use of cMRF in a patient
population-heart transplant recipients-and show initial results.
