What is the definition or description of: carotid ultrasound exam?

Its a imaging test: Its an imaging test for blockages in the arteries in the neck called the carotid ateries. No ivs are used. Its simply uses a gel and an ultrasound probe.

Two different Exams: Carotid intima-media thickness (cimt) ultrasound measures the thickness of the arterial wall. Subclinical vascular disease is present if: 1. Mean cimt or max cimt is > the 75th percentile for a patient's age, gender and ethnicity; 2. A "plaque" is identified (focal thickening > 1.5 mm or thickening > twice the adjacent tissue). Duplex scans evaluate the amount of blood flowing through the vessels.

Evaluate blood flow: It looks at the degree of narrowing and also evaluates the velocity of blood flow. These parameters combined help make diagnosis of carotid artery disease.
