INTERVENTIONAL
Conditions
Summary
The purpose of the study is to quantitatively characterize the flow in the pelvic venous structures using 2D and 4D flow MRI with the objective of establishing physiologic and pathologic parameters for downstream computational fluid dynamics analysis. Arm 1: To establish the baseline flow characteristics of the iliac veins in patients with no imaging evidence of iliac venous disease. Arm 2: To assess the flow characteristics of the iliac veins in patients with left iliac vein compression syndrome (a.k.a. May-Thurner syndrome). Arm 3: To assess the flow characteristics of the iliac veins in patients status post iliac stent placement.
