A retrospectively triggered approach to high temporal
resolution dynamic T1 quantification in small rodent
myocardium is demonstrated. An inversion recovery
snapshot FLASH method is used. The retrospective
approach allows to correct for drift in the triggering
and to chose the highest temporal resolution afforded by
SNR. A Manganese Enhanced MRI (MEMRI) experiment in rats
is shown. The drift in triggering is corrected
automatically and a temporal resolution of 66s is
achieved.
