plaque morphology

Full Definition

The detailed structural analysis of atherosclerotic plaques, including composition (lipid core, fibrous cap, calcification), surface characteristics (smooth, irregular, ulcerated), and vulnerability features that determine risk of rupture or embolization. Advanced imaging techniques such as intravascular ultrasound, optical coherence tomography, and near-infrared spectroscopy allow detailed assessment of plaque morphology to guide treatment decisions and risk stratification in patients with coronary and peripheral arterial disease.

Usage

Usage note: Often paired with specific imaging modality (IVUS plaque morphology, OCT plaque morphology).

In Context

• "OCT imaging revealed complex plaque morphology with thin fibrous cap and large lipid core." — Imaging report
• "The heterogeneous plaque morphology suggested high risk for distal embolization during intervention." — Pre-procedural assessment
