Total Liver Health in One Exam
MR Elastography (MRE) measures stiffness by assessing four images across the entire liver, resulting in a comprehensive and incredibly accurate diagnosis not available with other non-invasive technologies. In addition to a stiffness score measured in kPa, clinicians and patients often receive color-coded maps of their liver fibrosis, called Elastograms. In these intuitive maps, red corresponds to highly advanced fibrosis, while purple represents healthy liver tissue.
When to use MRE
MR Elastography is able to overcome many confounding factors that can impact the performance in other non-invasive technologies. Notably for fatty liver disease, this most often includes BMI and increased waist circumference, as ultrasound-based elastography (e.g., Fibroscan®) methods often perform poorly in these patient groups.
Because MRE is not affected by waist circumference or obesity, clinical guidelines recommend that MRE be incorporated into the clinical workflow to reliably estimate the degree of fibrosis present. Clinicians may also request fat fraction measurements (for steatosis), inflammation, and/or malignancy via traditional MR workup, resulting in a powerful and comprehensive liver assessment.

Clinical guidance suggests that the utilization of MR Elastography increases as BMI increases
“In adults with NAFLD and a higher risk of cirrhosis, MRE is suggested, rather than VCTE, for detection of cirrhosis”
