The sound waves are harmless and the gel is easily removed off your skin. Objective: To evaluate carotid imaging pathology by CDU in stroke patients. When the transducer is placed on the chest at certain locations and angles, the sound waves. Carotid pathology is known to be associated with strokes, and carotid doppler ultrasonography (CDU) is a powerful tool for use in evaluating atherosclerosis of the carotid artery. During the procedure, a transducer (like a microphone) sends out sound waves at a frequency too high to be heard. The doctor will provide you with results and recommendations for prevention and/or treatment right after completion of the test.Īre there any risks I should be aware of? An echocardiogram is a noninvasive (the skin is not pierced) procedure used to assess the hearts function and structures. Pictures are displayed on the computer recording the results of the echoes. This sound is not audible by the human ear. The gel will help the transducer give off ultrasound waves and detect their echoes as they bounce off the arterial walls and blood cells. Gel will be applied on your neck where the carotid arteries are located. Typically performed by a technician, you will be asked to lie on your back on an exam table holding still. The carotid ultrasound is a painless and non-invasive test. No preparation for this test is necessary. What to expect before, during, and after? Your doctor wants to check for restoration of blood flow through the artery following carotid artery surgery (carotid endarterectomy) or to check correct positioning of a stent following carotid stenting.Your doctor suspects blood clots in one of your arteries.Your doctor hears an abnormal sound in your carotid arteries (carotid bruit) Transthoracic echocardiography and carotid Doppler ultrasound for detection of cardiac and carotid artery disease in patients with acute retinal artery.Hardened plaque cases narrowing of the carotid arteries and reduces the flow of oxygen-rich blood to the brain while ruptured plaques form clots which prevent blood flow through a carotid artery, thereby causing a stroke.Ī carotid ultrasound may be recommended if: Over time, the plaque can either harden or rupture. This condition is called carotid artery disease. These echoes are then sent to a computer and seen on a screen as images or video. The carotid doppler ultrasound uses the blood flow through your carotid arteries to check for the presence of plaque buildup. The sound waves echo off the blood cells. The internal carotid arteries supply oxygen-rich blood to your brain while the external carotid arteries supply oxygen rich blood to your face, scalp, and neck. Background and PurposePatients with transient ischemic attack require carotid imaging to diagnose carotid stenosis.The differing sensitivity/specificity and availability of carotid imaging methods have created uncertainty over whichnoninvasive method is best and whether intra-arterial angiography is still required. There is a common carotid artery on each side of your neck and each divide into internal and external carotid arteries. A carotid ultrasound uses high-frequency sound waves or echoes to create pictures of the insides of your carotid arteries.
