The feasibility of cardiac T1 mapping in mouse is demonstrated at 9.4T using Multitasking, an ECG-free and free-breathing technique. High spatial- and temporal-resolution T1 maps of healthy mouse hearts without either respiratory or cardiac triggering were obtained. This technique simplifies experimental setup and opens possibilities of investigating numerous heart disease/transgenic mouse models.
