 Abstract: B0 inhomogeneities are a major challenge at ultra-high magnetic field strengths (B0 ≥ 7 T), as they can lead to strong image artifacts. In this work, a B0 shimming routine that is based on 23Na B0 maps was implemented for applications in X-nuclei imaging where no 1H MRI data can be acquired and therefore, no vendor-provided shimming routines can be used. The proposed 23Na ConsTru shimming routine showed an improvement in B0 homogeneity comparable to the vendor-provided GRE Brain shimming routine both in phantom and in vivo measurements using 23Na B0 map acquisition times less than 1 minute.
