What is a Carotid Artery Ultrasound?

A carotid artery ultrasound (also called a carotid artery duplex) is an ultrasound-based diagnostic imaging technique to reveal structural details of the carotid arteries, so as to look for blood clots, atherosclerotic plaque buildup (carotid artery disease), and other blood flow problems.

How to Prepare for a Carotid Duplex Scan?

To get the best results, please use the following instructions for your carotid ultrasound:

  • Wear comfortable clothes with a no collar or open collar shirt

  • Do not wear any necklaces or dangling earrings

  • Take your regular scheduled medication unless otherwise instructed by the ordering doctor.
