Ultrasound breakthrough could end misdiagnosis of leg swelling disorders
NCT ID NCT07489248
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses special ultrasound techniques to find clear differences between lymphedema and lipedema, two chronic conditions that cause leg swelling and are often hard to tell apart. Researchers will compare 75 adults—those with lymphedema, those with lipedema, and healthy volunteers—using non-invasive imaging. The goal is to create a reliable, painless way to diagnose these conditions early, helping doctors choose the right treatment.
