MR elastography is a promising new biomarker for quantifying liver fibrosis. This work investigates several ROI placement strategies for the analysis of MRE elastogram data, including a wave detection confidence method, and whether they improve correlation of the stiffness estimates with established histopathological grading schema and semiautomated collagen analysis with Sirius Red staining. These data indicate that using more sophisticated analysis strategies based on mean stiffness region of interest values makes no discernible difference to the correlation with liver biopsy grading.
