A Duplex Carotid Ultrasound is a safe, non-invasive procedure used to examine your carotid artery and potentially diagnose problems. It uses high-frequency sound waves (ultrasound) to obtain images and waveforms of the carotid arteries. The carotid arteries run along each side of the neck supplying the brain with oxygen-rich blood. The ultrasound images will show the structure of the carotid artery. The doppler will show the volume of blood flow through the artery.
How is the test done?
Carotid ultrasounds are routinely performed in the Heart Clinic of Louisiana Ultrasound department. During the test you will be asked to lie on your back on an examination table while your neck is supported and slightly elevated. The technician places a hand-held transducer against your neck and slowly passes the transducer along the carotid artery. Ultrasound gel is used on the transducer to help it slide across the neck. The test should take about 30 minutes.
How do I prepare for the test?
There is no special preparation required for a carotid ultrasound. A normal diet may be consumed and all medications should be taken as prescribed.
