Magnetic resonance elastography (MRE), a non-invasive method to quantify liver stiffness, has not been directly correlated with MR-targeted biopsy results. We tested the hypothesis that real-time MR-guided biopsies could target focal segments of liver for histopathologic correlation with MRE stiffness measurements. Our results demonstrate the feasibility of real-time MR guidance to biopsy focal liver segments for correlation of fibrosis using MRE targets. Since early-stage hepatic fibrosis can present as focal lesions, MRE can be used to target biopsies to avoid clinical understaging and delayed initiation of therapy.
