Fig 2.
Color-coded ‘Dual-τ Dual-FA’ images of (a) PD, (b) T1, and (c) T2 in the three-tube bottle gel phantom. Part (d) shows an AFI B1 map of the phantom. Part (e) plots the ‘Dual-τ Dual-FA’ T vs. the standard PS T1 for each compartment. Part (f) plots the ‘Dual-τ Dual-FA’ T2 vs. SE T2 in the compartments (above 150ms, the ‘Dual-τ Dual-FA’ T2 is not accurate[14]). The black lines denote identity. The scales of PD is in pu, T1 and T2 maps are in ms, and the B1 map is % of the nominal FA.
