vessel wall imaging
Also written as: VWI — vessel wall imaging
Specialized MRI technique focused on visualizing arterial wall composition and pathology rather than luminal anatomy.
Full Definition
Vessel wall imaging is an advanced magnetic resonance imaging technique specifically designed to evaluate arterial wall composition, inflammation, and pathological changes rather than conventional luminal assessment. This specialized imaging approach employs high-resolution sequences with blood flow suppression to enable detailed visualization of vessel wall thickness, plaque composition, hemorrhage, and inflammatory activity. The technique is particularly valuable for assessing vulnerable plaque characteristics, monitoring inflammatory arteriopathies, and evaluating treatment response in conditions such as atherosclerosis and vasculitis. Modern vessel wall imaging protocols can differentiate between fibrous tissue, lipid core, calcification, and hemorrhage within arterial walls.
Usage
Usage note: Distinguish from conventional angiographic imaging; often abbreviated as VWI in research contexts.
