Carotid Ultrasound

Carotid ultrasound is used to evaluate for plaque and blood flow obstructions in the carotid artery. It can be used to assess the risk factor for stroke and can also be used post-operatively to verify the success of interventional procedures.

Ultrasound imaging uses high-frequency sound waves to produce ultrasound images of the body’s tissues, structures, and blood flow. A transducer/probe and ultrasound gel work together to transmit and receive sound waves to produce images on the monitor. The transducer sends sound waves into the body, and the echoes are used to create images of the blood vessels in the side of your neck.

Warm, water-based gel will be applied to the ultrasound transducer or directly on the skin. The sonographer will then move the transducer around to obtain clear images of the underlying structures for the physician to interpret. The sonographer presses the transducer against the side of your neck to capture detailed images of the carotid artery and assess blood flow.

Before the test is administered, you may be asked to change into a gown and remove any neck/ear accessories.

The benefits of Carotid Ultrasound:

• Ultrasound images can be shown in real-time as they happen.
• The exam is painless and non-invasive.
• No ionizing radiation is used for this procedure.

Risks you should be aware of:

• There are no known risks for ultrasound.

Additional Information

A carotid ultrasound exam typically takes about 30 minutes. It can help detect blood clots, plaque buildup, and other abnormalities that increase the risk of stroke. Using Doppler ultrasound, the exam can also assess the movement of blood cells within the blood vessels. Patients with high blood pressure or other risk factors for heart disease and stroke may benefit from this imaging test to monitor their carotid arteries and overall vascular health.
