A time-efficient multi-slice ECG gated Look-Locker sequence is developed for multi-slice T1 mapping in the mouse heart. With this sequence, multi-slice T1 maps can be generated for the mouse heart in less than 10 minutes. Multi-slice T1 mapping was tested in phantoms and in a CD-1 mouse, and it was found that T1 measurements agreed with single-slice T1 measurements within 4% for the phantom and within 10% in vivo. This sequence will have great applicability for multi-slice arterial spin labelling perfusion measurements to study cardiac disease models.
