Carotid Duplex Scan

Carotid duplex scans use high-frequency sound waves to visualize the vessels and evaluate the two carotid arteries, which are located on each side of the neck and carry blood from the heart to the brain. Using a specialized Doppler technique, we can also measure the movement of blood within the vessels. This provides detailed pictures of these blood vessels to help physicians determine the extent and cause of restricted blood flow.

Common Questions

  • Why would my physician recommend Carotid Duplex Scan?

    Your physician may recommend a carotid duplex scan if you have a suspected blockage or narrowing of the carotid arteries, if you have high blood pressure, if your physician hears an abnormal sound over an artery using a stethoscope, or in preparation for or after coronary artery bypass surgery.

  • What do I need to do before my procedure?

    You will be given detailed instructions by our staff before your procedure. Be sure to bring your insurance card, photo ID, list of current medications (dose and frequency) and any diagnostic testing results.

  • What should I expect during a Carotid Duplex Scan?

    You will lay face-up on a moveable exam table and you may be turned to either side. Warm gel is placed over the area to be tested and a probe is gently passed back and forth on your skin over the area to create and pick up sound waves, which are converted into an image on a screen. During the exam, you will hear the ultrasound machine reproduce your pulse as detected through the Doppler component of the exam.

  • What should I expect after a Carotid Duplex Scan?

    When the imaging is complete, the clear gel will be wiped off your skin. After the procedure, you may resume your normal activities immediately.
