Vascular disease is a common disease, including arteriosclerosis, arterial stenosis, venous thrombosis, etc. These diseases not only affect the physical health of patients, but may also cause serious cardiovascular events such as myocardial infarction and stroke. Therefore, early diagnosis and treatment of vascular diseases are of great significance for ensuring the safety of patients. Medical ultrasound scanners, as a non-invasive, painless, fast, and accurate diagnostic tool, play an important role in the diagnosis of vascular diseases. This article will introduce the application of medical ultrasound scanners in the diagnosis of vascular diseases.

2、 The principles and advantages of medical ultrasound scanners

Medical ultrasound scanners utilize the propagation characteristics of high-frequency sound waves in human tissues to scan blood vessels and obtain information on their morphology, structure, and blood flow. Compared to traditional angiography, medical ultrasound scanners have the following advantages:

Non invasive: Ultrasound scanning does not cause trauma to the human body, avoiding potential allergic reactions and kidney function damage caused by contrast agents.

Real time: Ultrasound scanning can obtain real-time blood flow information of blood vessels, which helps doctors to timely understand changes in the patient's condition.

Accuracy: Ultrasonic scanning can accurately measure parameters such as the diameter, thickness, and blood flow velocity of blood vessels, providing doctors with accurate diagnostic basis.

Convenience: Ultrasonic scanning is easy to operate, has good repeatability, and is suitable for large-scale screening and follow-up.

3、 The application of medical ultrasound scanner in the diagnosis of vascular diseases

Atherosclerosis diagnosis: Atherosclerosis is one of the most common types of vascular diseases. Ultrasound scanning can detect the thickening and calcification of arterial walls, evaluate the degree and extent of atherosclerosis. Meanwhile, by measuring parameters such as blood flow velocity and resistance index, the severity and prognosis of arteriosclerosis can be determined.

Diagnosis of arterial stenosis: Arterial stenosis is one of the important causes of myocardial infarction and stroke. Ultrasound scanning can detect the location and degree of arterial stenosis, providing accurate diagnostic evidence for doctors. Meanwhile, by measuring parameters such as blood flow velocity and resistance index, the severity and prognosis of arterial stenosis can be determined.

Diagnosis of venous thrombosis: Venous thrombosis is one of the important causes of serious complications such as pulmonary embolism. Ultrasound scanning can detect the location and extent of venous thrombosis, providing accurate diagnostic evidence for doctors. Meanwhile, by measuring parameters such as blood flow velocity and resistance index, the severity and prognosis of venous thrombosis can be determined.

Diagnosis of Vascular Inflammatory Disease: Vascular inflammatory disease is a common immune disease, such as nodular polyarteritis, Kawasaki disease, etc. Ultrasound scanning can detect vascular inflammation and provide accurate diagnostic evidence for doctors. Meanwhile, by measuring parameters such as blood flow velocity and resistance index, the severity and prognosis of vascular inflammation can be determined.

4、 Conclusion

Medical ultrasound scanners, as a non-invasive, painless, fast, and accurate diagnostic tool, play an important role in the diagnosis of vascular diseases. By obtaining real-time information on the morphology, structure, and blood flow of blood vessels, accurate diagnostic criteria are provided for doctors. Meanwhile, ultrasound scanning is easy to operate and has good repeatability, making it suitable for large-scale screening and follow-up. Therefore, medical ultrasound scanners have broad application prospects in the diagnosis of vascular diseases.
