Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
