Non-Invasive Carotid Imaging: A Comparative Assessment and Practical Approach

Area of Science:

• Neurology
• Vascular Surgery
• Radiology

Background:

• Carotid artery disease is a leading cause of stroke, contributing significantly to patient morbidity and mortality.
• Both medical and invasive treatments for carotid artery disease can improve patient outcomes.

Purpose of the Study:

• To review noninvasive imaging modalities for assessing the extracranial carotid artery.
• To provide a framework for using imaging in the clinical evaluation of carotid artery disease.

Main Methods:

• Discussion of duplex ultrasonography.
• Review of computerized tomographic angiography (CTA).
• Evaluation of magnetic resonance angiography (MRA).

Main Results:

• Each imaging modality (duplex ultrasonography, CTA, MRA) has distinct advantages and limitations.
• Imaging assessment guides clinical decision-making for carotid artery disease management.

Conclusions:

• Noninvasive imaging is crucial for evaluating patients with carotid artery disease.
• Understanding the strengths and weaknesses of different imaging techniques optimizes patient care and outcomes.
