What diseases are mainly examined and screened by carotid artery color ultrasound? Who is it for?

Carotid ultrasound is mainly used to check the state of blood vessels in the neck, such as checking whether there is stenosis in local blood vessels. Usually dizzy.

If you have symptoms, you can go to the hospital immediately for a neck vascular examination and have symptoms based on the test results**. Pay attention to your diet. It is better to be careful not to eat greasy food and take good care.

Carotid color Doppler ultrasound is the current stage to confirm whether the carotid arteries are atherosclerosis.

The most commonly used test for disease. Many people have tried it, and even if they are not in the hospital, there is a good chance that the medical examination center will do this test. This test can determine whether there is plaque in the carotid artery and whether the nature of the plaque is clear.

For example, plaques are soft, mixed, or hard plaques. This provides strong support for how to ** in the next phase.

CT with carotid artery enhancement (CTA) can also detect carotid artery spots and determine the degree of stenosis. However, carotid CTA is not recommended as an initial test. The main thing is that it takes a lot of money and is radioactive.

Injection of contrast agent is also required.

Like the CT mentioned earlier, MRA can be used to perform the MRI - intensive examination, which is commonly used in medicine. The MRA on the general arch allows the aortic arch to be clearly seen.

On the arterial vessels, this test can be performed on patients in some cases, but this examination is not recommended as a superbody.

Examine. The main reason is that it is expensive, and color ultrasound of the carotid artery is also very convenient.

Not to mention carotid arteriography, which is probably the most reliable means of seeing the carotid arteries. It is medically known as a contraindication criterion. However, it is more expensive and belongs to the creation of examinations, so it is not suitable for physical examinations and the initial body of diseases.

At this stage, we do not know if the carotid artery is spotted, narrowed, or if it is of the nature of the spot, and the best way is to color the carotid artery first. For most people, it's definitely recognizable at a glance. A small number of people may require further testing, which can be done under the guidance of a clinical specialist.

As the preferred non-invasive carotid artery examination method, it has the characteristics of simplicity, safety and low cost. Not only can anatomical images of the carotid arteries be displayed, but plaque morphology can also be examined, such as distinguishing between intraplaque bleeding and plaque ulcers.

Arterial blood flow, flow velocity, direction of blood flow, and intra-arterial thrombus can also be displayed.

That's what I often tell you about CTA that can find arterial calcified spots. Useful for diagnosis and determination of options. This is because the extracranial carotid artery, which combines CT enhancement technology with thin-layer, large-scale, and rapid scanning technology, clearly displays the details of blood vessels in various parts of the body through reasonable post-processing, and is suitable for CTA examination.

The carotid artery is perpendicular to the CT section, hence the spiral CT scan.

, it can avoid the disadvantage of the relative lack of blood vessel decomposition force in the horizontal direction.

Carotid artery color ultrasound mainly checks the degree of arteriosclerosis, as well as whether there are serious problems in the coronary arteries, and whether there are serious problems in the heart and blood vessels, so patients with diabetes, hypertension, hyperuricemia, etc. are generally recommended to do carotid color ultrasound.

Answer] :d two-dimensional ultrasound shows that the diameter of the tumor is enlarged, the blood in the tumor is turbulent, and the CDFI shows that the tumor is embedded with a stupid embedded blood flow signal.

Carotid artery stenosis, carotid artery traumatic embolism, upper limb deep scarcity thrombosis, aortic valve stenosis, cerebral arteriosclerosis, arteriosclerotic occlusive disease, cerebral embolism, carotid arteriosclerosis remorse.

Carotid ultrasonography provides a non-invasive, simple, and reproducible method for the diagnosis of atherosclerosis. However, multi-parameter analysis should be advocated in the analysis of test results, and in addition to the flow rate of the relevant vascular segments, the pulsatile index, spectral morphology, blood flow direction and blood flow sound should also be considered. Carotid artery ultrasonography is helpful to determine the nature and stability of carotid atheroplaque in patients with ischemic cerebrovascular disease, determine the degree of carotid atherosclerosis and carotid artery stenosis, especially in showing the changes in arterial wall structure, and provide an objective basis for the early prevention and improvement of atherosclerosis.

Abnormal results: Carotid artery ultrasound can not only clearly show whether the intima of the blood vessel is thickened, whether there is plaque formation, the location and size of plaque formation, whether there is vascular stenosis and the degree of stenosis, whether there is occlusion, etc., but also can accurately measure and locate, and can also analyze the hemodynamic results of the detected artery. In particular, it can detect the presence of early carotid atherosclerotic lesions, so that patients can be prevented in time; The timely diagnosis of moderate to severe carotid artery stenosis and occlusion can be used as a strong basis for clinical selection of carotid endarterectomy**.

People who need to be examined: Patients with cardiovascular disease.
