In ultra-high field 7 Tesla (T) MRI, signal intensity variation or inhomogeneity are caused by main magnetic field (B0) and RF field (B1) inhomogeneity, susceptibility effects, and inhomogeneous coil sensitivity. We tested a post-processing technique available with SPM8, for signal intensity correction of various scan sequences on 7 T MRI. We found that by using SPM8, signal inhomogeneity was successfully corrected and a reduction in signal non-uniformity between the subcortical and deep white matter was observed.
