New MRI technique reveals hidden details of the achilles tendon
NCT ID NCT03287596
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study used a special MRI technique to create detailed maps of the Achilles tendon in 121 adults. Researchers compared healthy volunteers to people with a type of arthritis called spondyloarthropathy, both with and without tendon pain. The goal was to better understand tendon changes in these conditions, not to test a treatment.
