Reshaping the Standard: MRI Muscle Composition for Treatment Evaluation and Differentiation in Metabolic Disease and Beyond
Summarizing almost two decades worth of research developing and validating standardized MRI muscle biomarkers for use in research from academia and large-scale population studies, to multi-site clinical trials globally and all the way into the clinic:
- Establishing technical performance, from standardized acquisition protocols to image calibration, automatic segmentation, manual quality control, and robust measurement algorithms
- Making MRI muscle composition interpretable by publishing normative data, describing natural progression, and associations with physical function and mortality
- Enabling description of treatment effects independent of weight change and improving the prediction to outcomes using muscle volume z-score – a personalized weight and BMI-invariant muscle metric
- Providing published reference data showing change in MRI muscle composition across weight management therapies for contextualization of study results: liraglutide, tirzepatide, semaglutide, as well as gastric bypass & sleeve surgery
