Doppler Ultrasound Vascular Flow Studies
Detecting any narrowing of the arteries
Doppler ultrasound flow studies – uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Doppler technique is used to measure and assess the flow of blood.
A carotid Doppler ultrasound is a diagnostic procedure that uses high frequency sound waves to generate images of the carotid arteries within the neck. The carotid arteries supply oxygen-rich blood to the brain and this test allows Dr. Wolfson to detect any narrowing of the arteries.
This test is most commonly performed on patients who:
- Recently had a stroke
- Have an abnormal sound in the carotid artery
- Routine screening in patients at risk for carotid disease
- Recently had carotid artery surgery
Other arteries that are assessed by ultrasound include the abdominal aorta and the lower extremities. These tests can diagnose aneurysms and blockages in the legs that may lead to claudication (leg pain with ambulation).
During the ultrasound procedure, the patient will lie on their back and the technician will apply a cool gel to the area where the arteries are located. A transducer will then be moved over the area to give off sound waves and produce images of the arteries, which are displayed on a computer screen during the test. Ultrasound testing usually takes less than 30 minutes for the area scanned.
