A carotid artery screening also known as a duplex
scan is an abbreviated vascular ultrasound study
done to assess the blood flow and wall structure of
the arteries in the neck that supply blood from the
heart to the face and brain. There are six carotid
arteries - three on each side: the common carotid
artery CCA, which divides and form the internal carotid artery ICA and the external carotid artery ECA is shaped much like the letter "Y".
The screening is noninvasive and the term "duplex"
refers to the fact that two modes of ultrasound are used - Doppler and B-mode. The Doppler portion
evaluates the velocity and direction of blood flow to
indicate stroke risk and the B-mode obtains the
image of the intima and media wall thickness IMT for heart disease risk.
