Carotid duplex ultrasound: An imaging procedure that uses high-frequency sound waves to view the carotid arteries to determine if there is narrowing. This is the most common test utilized to evaluate for the presence of carotid artery disease. Carotid angiography Duplex ultrasound and magnetic resonance angiography compared with digital subtraction angiography in carotid artery stenosis: a systematic review. Stroke . 2003;34(5):1324–1332.
Duplex scan to evaluate for carotid artery stenosis is considered medically necessary for ANY of the following indications: 2021-04-06 · A recent study suggests that $33 million to $49 million are spent annually on low‐value carotid ultrasound, carotid computed tomography, and carotid magnetic resonance imaging for Medicare patients with syncope in the absence of signs of stroke or TIA. 6 As such, better quantifying the amount of unnecessary diagnostic carotid ultrasound screening is critically important for both clinicians Carotid duplex ultrasound, also known as carotid artery Doppler sonography, is a painless test to diagnose any blockages in the carotid arteries located along both sides of your neck. This scan uses two types of ultrasound to provide an accurate picture of the blood vessels as well as show how blood is flowing through them. Duplex ultrasound examination of the carotid arteries using high-resolution realtime imaging and pulsed Doppler flow measurements with velocity spectrum analysis was performed on a series of 50 consecutive patients (100 vessels), and findings were compared with findings of conventional carotid arteriography. Carotid duplex ultrasound after carotid stenting John Swinnen Department of Vascular Surgery, Westmead Hospital, Westmead, New South Wales 2145, Australia. Correspondence to John Swinnen via ASUM.

A hand-held electronic device is moved up and down the neck with ultrasound gel which enables ultrasound waves to travel and capture 2-dimensional, Doppler (blood flow) and 3-dimensional images of the Carotid arteries. The carotid doppler ultrasound requires a sonographer trained in vascular ultrasound which will increase the cost of the test. You often need to justify why you want the test to the insurance company in order for them to pay for it. Carotid IMT Ultrasound.
