Inhomogeneities in the static (B0) and transmitted (B1) magnetic fields can lead to artifacts and image degradation for a large variety of imaging applications. Quantitative MRI applications that fail to account for B0 and B1 inhomogeneities may suffer from substantial errors. Understanding the range of expected B0 and B1 inhomogeneities experienced in vivo is essential to engineer solutions aimed at avoiding or correcting for these effects. In this work, we measure the B0 and B1 inhomogeneities in the liver of 60 and 312 patients, respectively, at both 1.5T and 3.0T.
