Figure 5.

The sensitivity of the MTC quantification to B₁ inhomogeneity was evaluated using a synthetic MRI technique. (A) An illustration of the validation process. The synthetic MTC-MRF images were generated with the simulated relative B₁ (rB₁) and the reference tissue maps and fed to the trained RNN. The nominal scan parameters (${\text{p}}_{\text{scan}}^{\text{nom}}$) and corrected scan parameters (${\text{p}}_{\text{scan}}^{\text{corr}}$) were used to estimate the quantitative water and MTC maps. (B) Difference images between the reference and the estimated tissue maps are shown.
