Duplex carotid ultrasound

Duplex carotid ultrasound is a non-invasive medical imaging test that uses high-frequency sound waves to produce images of the carotid arteries in the neck. It’s a combination of two tests:

1. B-mode ultrasound: Creates images of the artery’s structure and any plaque buildup.
2. Doppler ultrasound: Measures blood flow velocity and detects any blockages or stenosis (narrowing).

The test is used to:

• Diagnose carotid artery disease (CAD)
• Identify plaque buildup or blood clots
• Detect stenosis or occlusion (blockage)
• Monitor blood flow and detect any changes
• Evaluate symptoms like dizziness, fainting, or stroke

During the test:

• A probe (transducer) is placed on the neck
• Gel is applied to improve sound wave transmission
• The probe sends and receives sound waves
• Images and blood flow data are displayed on a monitor

Duplex carotid ultrasound is a valuable tool for healthcare professionals to diagnose and manage carotid artery disease, helping to prevent stroke and other cardiovascular events.
