vessel wall enhancement
Abnormal uptake of contrast agent by the arterial wall indicating inflammation, infection, or other pathological processes.
Full Definition
Vessel wall enhancement refers to the abnormal uptake of contrast agent by the arterial wall tissues, visible on contrast-enhanced imaging studies. This finding typically indicates underlying pathological processes such as arteritis, infection, atherosclerotic inflammation, or vasculitis. The pattern, intensity, and distribution of enhancement provide important diagnostic clues for various vascular diseases and help distinguish between different etiologies of arterial pathology.
Usage
Usage note: Distinguish from luminal enhancement which refers to contrast within the vessel lumen.
In Context
- "The report noted circumferential vessel wall enhancement in the superficial temporal artery, consistent with giant cell arteritis." — Radiology report
- "Vessel wall enhancement was absent, arguing against active vasculitis in this patient." — Clinical interpretation
