Carotid ultrasound is called carotid color ultrasound Doppler flow imaging, which can determine whether the carotid arteries are narrowed and the degree of stenosis by observing the blood flow image.
Normal blood flow is bright in the middle and relatively weak in the periphery. When a “filling defect” is found, it often suggests the existence of stenotic lesions, and the carotid artery stenosis rate can be determined by blood flow imaging. Carotid artery stenosis rate color ultrasound has the following clinical applications:
1. To determine the degree of carotid atherosclerosis and plaque status.
2. For screening of patients with stroke risk factors and carotid artery stenosis risk factors.
3. For carotid artery screening in patients with transient retinal ischemic lesions or transient neurological symptoms and cerebral infarction.
4. For the auxiliary diagnosis of subclavian artery steal syndrome, congenital internal carotid artery muscle fiber dysplasia, internal carotid artery aneurysm, aortitis.
Carotid ultrasound is a very important examination, once found abnormal, please consult a doctor in time.
