Characterizing pelvic vein flow using advanced MRI techniques

Official title: Pelvic Vein Quantitative Flow Characterization Using 2D and 4D Flow MRI

Run by University of Massachusetts, Worcester · NCT06888024 · Data updated 2026-11-12

This study is testing how blood flows in the pelvic veins of healthy people, those with May-Thurner syndrome, and patients with iliac stents to better understand these conditions.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals with May-Thurner syndrome, those who have had iliac stent placement, or healthy individuals without venous disease.

Probably not a fit

Patients with contraindications to MRI or those with a history of pelvic or iliac venous disease may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to quantitatively analyze the flow in pelvic venous structures through 2D and 4D flow MRI. It includes three arms: one to establish baseline flow characteristics in healthy individuals, another to assess flow in patients with May-Thurner syndrome, and a third for those who have undergone iliac stent placement. The goal is to create physiologic and pathologic parameters that can inform future computational fluid dynamics analyses.

Why it matters

Potential benefit: If successful, this study could enhance the understanding and treatment of iliac venous diseases, potentially leading to improved patient outcomes.

How similar studies have gone: While the specific approach of using 2D and 4D flow MRI for this purpose may be novel, similar studies have shown promise in characterizing venous flow dynamics.
