Small Animal Look-Locker Inversion recovery (SALLI) is a novel imaging and reconstruction strategy allowing for simultaneous acquisition of cardiac T1 maps, cine movies, and IR-prepared images. Phantom experiments illustrate the T1 behavior of SALLI T1 maps using different sets of timing parameters. In-vivo images were obtained in a rat heart with acute anterior myocardial infarction and allowed to clearly identify the infarction site on all three modalities in a time-effective manner.
