Single breath-hold native MOLLI T1 mapping in 3 slices is possible using SENSE=4 & 6 and a 72 channel receive array. T1 values in 16 segments of the 17-segment AHA model (excluding the apical segment) were similar compared to SENSE=2 using 3 breath-holds measured in 20 healthy subjects (10 female). Myocardial T2 GRaSE mapping with fewer breath-holds in 3 slices is possible, though at the expense of decreased accuracy of the T2 values in specific segments.
