a) Schematic diagram of the proposed multi-slice T2 mapping sequence. Multiple single-shot images are acquired using ECG-triggering, following T2prep of different echo lengths, TET2P. An image, ISAT, is acquired directly after a saturation pulse to simulate the effect of a very long T2prep echo time b) The slice selective T2prep pulse consists of a tip-down slice selective 90˚ pulse, followed by four non-selective 180˚ refocus pulses (only two are illustrated in the figure) and ends with a closing tip-up slice selective 90˚ pulse. c) Slices are acquired in an interleaved fashion to allow sufficient T1 recovery time for each slice. The slice selective 90˚ pulses are applied with a slice thickness twice as imaging slice to minimize the impact of slice imperfection.
