Evaluation of B0-inhomogeneity correction for triple-quantum-filtered sodium MRI of the human brain at 4.7Â T

► Most of the brain experienced <10% signal loss due to B0 inhomogeneity at 4.7 T. ► B0 inhomogeneity correction did not improve SNR on TQF sodium human brain images. ► B0 correction is unnecessary for TQF sodium MRI within much of the brain at 4.7 T.
