vessel wall thickening

Full Definition

Vessel wall thickening refers to an abnormal increase in the thickness of blood vessel walls, typically measured on high-resolution cross-sectional imaging such as MRI or CT. This finding can indicate various pathological processes including atherosclerosis, vasculitis, or inflammatory conditions. In editorial contexts, this term must be distinguished from luminal narrowing, as wall thickening may occur with or without stenosis. Accurate measurement and description of wall thickness is crucial for radiological reporting and clinical decision-making.

Usage

Usage note: Ensure distinction from stenosis or luminal narrowing in reports.
