Carotid Artery Ultrasound

Procedure Overview

Carotid Artery Ultrasound at Gangnam Heartscan Healthcare Center is a non-invasive, radiation-free B-mode and Color Doppler ultrasound examination that evaluates the common, internal, and external carotid arteries in the neck. By measuring carotid intima-media thickness (IMT), characterizing atherosclerotic plaques, and assessing blood-flow velocity, the test provides a direct window into systemic vascular health and ischemic stroke risk.

Clinical Indications

• Cerebrovascular stroke-risk assessment through carotid stenosis, occlusion, and intima-media thickness (IMT) measurement
• Vascular screening for individuals with hypertension, diabetes mellitus, hyperlipidemia, metabolic syndrome, or smoking history
• Evaluation of dizziness, transient ischemic attack (TIA) symptoms, or cervical vascular bruits
• Ongoing monitoring of known carotid atherosclerotic plaques

How the Screening Works

1. Neck Positioning: The patient rests supine with the neck gently extended and turned slightly to allow clear acoustic access to both sides of the neck.
2. B-Mode & Color Doppler Scanning: A high-frequency linear ultrasound transducer measures arterial wall intima-media thickness (IMT), identifies plaque morphology, and records Doppler blood-flow velocities.
3. Vascular Risk Interpretation: Physicians evaluate luminal narrowing and hemodynamic flow profiles to stratify cerebrovascular and cardiovascular risk.

Preparation & Precautions

• No fasting or special dietary restriction is required for Carotid Artery Ultrasound.
• Wear an open-collar shirt or blouse and remove necklaces or dangling earrings before the examination.
• Bring previous carotid ultrasound reports if you are visiting for comparative plaque or IMT follow-up.
