Doppler is a physics term that allows the blood flow to be seen in colour and measured quantitatively. The sonographer will explain to you that you might hear some noise occasionally which is the Doppler ultrasound. You shouldn’t feel any discomfort during the procedure. ![]() The sonographer then gently presses the transducer against the side of your neck. The definition of peak systolic velocity varies between examiners when spectral broadening due to turbulence is present. The gel helps transmit the ultrasound waves back and forth. Angle adjusted Doppler velocity measurements produce higher values when higher Doppler examination angles are used. Warm gel will then be applied to your skin above the site of each carotid artery. The sonographer may position your head to better access the side of your neck with suitable pillow for extension. During the procedure, you’ll likely lie on your back during the ultrasound. A carotid ultrasound usually takes about 30 minutes. Please don’t wear a necklace or dangling earrings in order to provide area in neck for imaging. Wear a comfortable shirt with no collar or an open collar. The results can help your doctor determine a treatment to lower your stroke risk. This test can show narrowing or possible blockages due to plaque build-up in the arteries which increases the risk of stroke. His one great achievement is being the father of three amazing children.A carotid Doppler ultrasound is a non-invasive imaging test that uses ultrasound to examine the carotid arteries located in the neck. He is one of the founders of the FOAM movement (Free Open-Access Medical education) and is co-creator of , the RAGE podcast, the Resuscitology course, and the SMACC conference.
