Curve fitting examples when the RD_C++_multi-core method was used. (Top row) curve fits of the samples acquired using the pre-contrast MOLLI 5(3)3 protocol. (Bottom row) curve fits of the samples acquired using the post-contrast MOLLI 4(1)3(1)2 protocol. The left plots represent curve fitting on a voxel corresponding to the left ventricular blood pool, while the right plots represent curve fitting on a voxel corresponding to the myocardium. The solid blue line denotes the estimated T1 relaxation curve after fitting. Note that the nulling time typically ranges 200–400 ms for the post-contrast, and acquiring three samples instead of two in early TIs in post MOLLI is helpful in estimating short T1 values, which are typical in post-contrast tissue
