T₂*-weighted MRI at high field is a promising tool to detect and characterize multiple sclerosis (MS) lesions. However, its high sensitivity to motion-induced B₀ field changes limits the successful application of this technique in routine clinical use. In this study, we evaluated our recently developed motion and B₀ correction method using a navigator-based 3D GRE acquisition for imaging MS lesions at 7 T.
