High-field MRI to detect muscle changes in age-related muscle loss
Quantitative and Spectroscopic Imaging of Skeletal Muscle Changes in Sarcopenia at High Field
Very strong MRI scans will measure muscle quality, fat, and chemistry in older adults with sarcopenia.

What this research studies
You would complete leg muscle function tests and questionnaires and have a leg MRI on an ultra-high-field scanner to get very detailed images and spectroscopy. The team will extract biomarkers such as muscle shape, T2 relaxation, water diffusion, fat fraction, and lipid composition. Researchers aim to connect these imaging features to how well your muscles work and to how they respond to treatments. This supplement funds a research fellow who will consent participants, run study visits, process data, and communicate results.
Who could benefit from this research
Good fit: Older adults with known or suspected sarcopenia or unexplained leg muscle weakness who can travel to Boston for study visits.
Not a fit: People with MRI-incompatible implants, severe claustrophobia, or those without muscle loss are unlikely to benefit from this work.
Why it matters
Potential benefit: If successful, this could provide non-invasive imaging markers to track muscle health and help guide treatment for sarcopenia.
How similar studies have performed: Prior MRI work on muscle composition has been promising, but ultra-high-field imaging and spectroscopy for sarcopenia are relatively new.
