Characterizing pelvic vein flow using advanced MRI techniques
Pelvic Vein Quantitative Flow Characterization Using 2D and 4D Flow MRI
NA · University of Massachusetts, Worcester · NCT06888024
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.

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.
Who should consider this trial
Good fit: Ideal candidates include individuals with May-Thurner syndrome, those who have had iliac stent placement, or healthy individuals without venous disease.
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.
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 performed: 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.
