What is it?
Ultrasound or sonography exposes parts of the body to high frequency sound waves that produce pictures of particular areas of the body. This is a painless procedure that looks at the carotid arteries that flow up both sides of the neck.
I am coming in for this test, what can I expect?
There are no special instructions for this test other than wear loose fitting clothing and no jewelry. The test usually takes 30 minutes and if the doctor is seeing you after it could be a bit of a wait. Bring a book or magazine just in case you experience a wait.
Indications:
Carotid Doppler studies are used to demonstrate blocked or reduced blood flow in the arteries of the neck that could cause stroke. This test is also used to evaluate symptoms of dizziness, vision changes and loss of balance that may be caused by impeded or restricted blood flow through these vessels.
