Carotid Duplex Examination


A Carotid Duplex Examination is an ultrasound test of the carotid arteries in the neck that lead to the brain. This study is used to detect a blockage or narrowing of the carotid arteries which may cause a stroke.

The Carotid Duplex Examination takes about 30 minutes. There are no special preparations. You should where a loose fitting shirt or blouse that does not have a high neck. You will lie on an exam table in a darkened room while the technologist performs the exam.

Your doctor will receive the test results in approximately 2 working days.

What kind of symptoms might I experience if there were a blockage in my carotid arteries? There are several signs and symptoms that you may experience such as:

  • Carotid bruit (a noise or murmur heard in the neck when your doctor listens to your neck with a stethoscope)
  • Loss of balance
  • Vertigo (dizziness)
  • Aphasia (inability to speak)
  • Numbness or weakness on one side of your body
  • Amaurosis Fugax (transient blindness in one eye)
  • Syncope (fainting)
