New MRI technique could unlock secrets of pelvic vein disorders
NCT ID NCT06888024
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study uses special MRI scans to measure blood flow in the pelvic veins of 15 people. It includes three groups: healthy volunteers, people with May-Thurner syndrome (a compressed vein), and those who have had a stent placed. The goal is to create a detailed understanding of normal and abnormal blood flow, which could improve future diagnosis and treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors better diagnose and treat pelvic vein compression conditions like May-Thurner syndrome.
- What could go wrong
- This is a very small, early imaging study with only 15 participants, so results may not apply to everyone. It is not testing a treatment.
