Model-based myocardial T1 mapping with sparsity constraints using single-shot inversion-recovery radial FLASH cardiovascular magnetic resonance

Table 2 Myocardial T1 values (ms) and CVs in left-ventricular septum of eight subjects using single-shot IR fast low angle shot (FLASH) with nonlinear inversion (NLINV) reconstruction without and with a spatial filter, the proposed model-based reconstruction and modified Look-Locker inversion recovery (MOLLI), respectively
