Fig. 4.

Results from an in-vivo human acquisition. T1ρ weighted images reconstructed using the proposed multicoil 3D total variation formulation is shown in (a-d). The myocardial T1ρ map (e) showed good uniformity and low least squares fit error (f). T1ρ map with the breath-held 2D sequence acquired at the same slice position is shown in (g). The mean T1ρ estimated from the free-breathing 3D scans and breath-held 2D were 67.9 ± 4.5 ms and 71.4 ± 6.5 ms, respectively
