With the intensification of population aging, cerebrovascular diseases have become one of the main diseases threatening human health. Among them, stroke has become a global health problem due to its high incidence rate, high disability rate and high mortality. Early detection and treatment of stroke is of great significance for improving patients' quality of life and reducing social burden. In recent years, with the continuous development of medical technology, ultrasound scanners have played an increasingly important role in the screening and evaluation of stroke patients.

1、 Introduction to Ultrasonic Scanners

Ultrasonic scanner is a technology that utilizes high-frequency sound waves to propagate within the human body, generate images by receiving reflected sound signals, and observe internal organs and tissues of the human body. It has the advantages of non-invasive, radiation free, and easy operation, and has been widely used in the field of clinical medicine.

2、 Stroke screening and assessment

Stroke screening mainly includes the examination and evaluation of stroke risk factors, as well as the screening of suspected stroke symptoms. These risk factors include hypertension, diabetes, hyperlipidemia, heart disease, smoking, alcoholism, etc. Assessing stroke symptoms mainly includes neurological examination and imaging examination of the patient.

In imaging examinations, ultrasound scanners have unique advantages. By using neck vascular ultrasound and intracranial vascular ultrasound, the shape, structure, and blood flow of blood vessels can be clearly observed, thereby assessing the risk of stroke. In addition, ultrasound scanners can also detect abnormal cerebral blood flow perfusion, reflecting the degree of ischemia in brain tissue, which helps to evaluate the severity and prognosis of stroke.

3、 Application of ultrasound scanner in stroke screening

1. Cervical vascular ultrasound

Cervical vascular ultrasound can detect carotid artery stenosis, plaque formation, thrombosis, and evaluate the pathological changes of extracranial blood vessels. For people with stroke risk factors such as hypertension and diabetes, regular neck vascular ultrasound examination is helpful to detect vascular diseases as early as possible and prevent stroke.

2. Intracranial vascular ultrasound

Intracranial vascular ultrasound can detect stenosis, occlusion, thrombosis, etc. of intracranial arteries, thereby evaluating the pathological changes of intracranial vessels. For patients who have already experienced a stroke, intracranial vascular ultrasound can understand the progress of the condition and guide the selection of treatment plans.

3. Cerebral blood flow perfusion ultrasound

Cerebral blood flow perfusion ultrasound can detect the blood flow perfusion of brain tissue and reflect the degree of ischemia in brain tissue. For patients who have already experienced a stroke, cerebral blood flow perfusion ultrasound can assess the severity and prognosis of the stroke, guiding subsequent treatment and rehabilitation.

4、 Application of ultrasound scanner in stroke assessment

1. Vascular assessment

By using ultrasound scanners to evaluate blood vessels, it is possible to understand the degree of stenosis, thrombosis, plaque distribution, and other factors of stroke risk and prognosis.

2. Cardiac assessment

By conducting cardiac assessment using ultrasound scanners, the structure and function of the heart can be understood, thereby assessing the risk factors and prognosis of cardiogenic stroke.

3. Neurological system assessment

By evaluating the nervous system through ultrasound scanners, the morphology and structure of brain tissue can be observed, and the degree of injury and prognosis of stroke can be understood.

5、 Application Prospects

With the development of medical technology, the application of ultrasound scanners in the screening and evaluation of stroke patients will become increasingly widespread. In the future, through further research and practice, ultrasonic scanners will play a greater role in the following aspects:

1. Early diagnosis and prevention

By conducting regular neck vascular ultrasound examinations, risk factors for stroke can be identified early, effective preventive measures can be taken, and the incidence of stroke can be reduced.

2. Guidance on treatment and prognosis evaluation

Through intracranial vascular ultrasound and cerebral blood flow perfusion ultrasound examination, the pathological changes and prognosis of stroke can be understood, guiding the selection and adjustment of treatment plans.

3. Disease monitoring and rehabilitation evaluation

By conducting regular ultrasound scans, changes in the condition can be monitored and treatment effectiveness evaluated, providing a basis for subsequent treatment and rehabilitation.

In summary, ultrasound scanners have broad application prospects in the screening and evaluation of stroke patients. Through continuous research and practice, we will better utilize this technology to provide more timely and effective diagnosis and treatment services for stroke patients, helping them return to health and life.
