A method for T1 mapping of the myocardium based on the phase-sensitive inversion-recovery (mpPSIR) technique is presented. It was performed in ten patients with sub-acute myocardial infarction and provided T1 values in very good agreement with the modified Look-Locker imaging (MOLLI) sequence. With both methods, we could demonstrate differences in T1 values between normal and infarcted myocardium, both before and after administration of Gd-containing contrast agent. The novel mpPSIR methods is a valuable alternative to the MOLLI sequence.
