Imaging is essential for evaluation of blood vessels and of end-organ damage. In particular, vascular imaging is often imperative for diagnosis and follow-up of the disease. Information regarding both luminal blood flow and vessel wall changes is important. Conventional angiography generally provides information about blood flow, clot formation, and collateral blood flow; whereas CT and/or magnetic resonance (MR) angiography provide visualization of vessel wall thickness and fragility, aneurysm formation, and overall disease activity.
