Duplex carotid ultrasound
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:
- B-mode ultrasound: Creates images of the artery’s structure and any plaque buildup.
- 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.
