At high and ultrahigh field, R2* measurement can be dependent on the technique used due to non-exponential FID distortions caused by various factors. In this study, we compared R2* measurements obtained with three different techniques in a group of four healthy volunteers at 7 Tesla to assess their consistency. Our results demonstrate that R2* values measured with a 2D imaging technique is only comparable with those from a 3D technique when appropriate correction for the background field inhomogeneity effect is applied.
