MR elastography (MRE) allows
non-invasive evaluation of hepatic stiffness and samples a larger area of the
liver than liver biopsy. The high accuracy of MRE for liver fibrosis staging
suggests that MRE could potentially replace liver biopsy. MRE
has traditionally been performed using a GRE sequence. GRE, however, has SNR
limitations at higher field strengths that can result in under-sampling potentially
leading to erroneous stiffness values. SE-EPI is an alternative means of
performing MRE that has higher SNR, lower susceptibility related signal loss
and increased speed. In this work, we compared GRE and SE-EPI MRE across two
vendor platforms.
