carotid sonogram anchorage


A Carotid Doppler Ultrasound Scan is primarily use for assessing the blood flow in the arteries of the neck, which transport blood and oxygen to the brain.

Several Common Indications for the Exam:

  • Transient Ischemic Attacks (TIA or “mini stroke”)
  • Numbness/Weakness in arm or face
  • Neck Bruit (heard with stethoscope)
  • Dizziness/loss of balance
  • Visual disturbance in one eye

What to Expect

You will be asked to lie on an exam table with your neck slightly extended. Vascular Technologist will apply a small amount of gel to the side of the neck and place an ultrasound probe near the “Adam’s apple”. A mild to moderate pressure may be necessary to obtain detailed images of the carotid arteries. The technologist will calculate the velocity of blood flowing through the arteries and to determine the degree of narrowing, if present.

Exam Preparation

No preparation is necessary. You will be asked to remove any necklaces or low hanging earrings.

Test Results

In emergent cases, or if requested by your referring provider, a preliminary report of findings will be provided immediately following the examination. Final reports are typically available in the morning of the next business day.
