Vascular disease is a common disease, including Atherosclerosis, varicose veins, Deep vein thrombosis and so on. In order to accurately diagnose and treat these diseases, medical ultrasound scanners are widely used in the medical community. This article will introduce the application of medical ultrasonic scanner in the diagnosis of Vascular disease, and discuss its advantages and precautions.

1、 The principle of ultrasonic scanner:

Medical ultrasound scanners use high-frequency ultrasound to transmit and reflect through blood vessels and tissues, forming real-time images. The ultrasonic probe emits high-frequency sound waves into the patient's body. When the sound waves come into contact with tissues or blood, they scatter and reflect. The control system receives the echo signal and processes it, then generates an image. Through these images, doctors can observe the morphology, blood flow velocity, and abnormal conditions of blood vessel walls, thus making disease diagnosis.

2、 Application of ultrasonic scanners:

1. Diagnosis of Atherosclerosis: Atherosclerosis is a common arterial disease. Ultrasonic scanner can accurately measure the size, location and internal structure of plaque, helping doctors assess the severity of lesions. At the same time, ultrasound scanning can also detect the blood flow velocity and status of arteries, identify areas of stenosis or blockage, and provide a basis for surgical treatment.

2. Diagnosis of Varicocele: Varicocele is a disease of venous dilation and disintegration, commonly found in the lower limbs. Ultrasound scanners can observe and measure varicose veins, helping doctors understand the extent and extent of varicose veins. In addition, ultrasound scanning can also detect abnormal blood flow and thrombosis to guide treatment and surgical intervention.

3. Diagnosis of Deep vein thrombosis: Deep vein thrombosis is a common Vascular disease, which is easy to cause serious complications such as Pulmonary embolism. Ultrasonic scanner can quickly detect the presence and location of Deep vein thrombosis, evaluate the size and shape of the thrombus, and determine whether the blood flow is smooth. This is of great significance for early diagnosis and treatment.

3、 Advantages of ultrasonic scanners:

1. Non invasive: Ultrasound scanners are a non-invasive examination method that can avoid the risk of trauma in traditional angiography and the radiation hazards of radiation.

2. Real time monitoring: Ultrasound scanners can observe blood vessels and blood flow dynamics in real time, helping doctors quickly determine the condition of the lesion and guide treatment and surgery.

3. Clear imaging: Ultrasound scanners can clearly display the structure and blood flow of blood vessels, and have high accuracy in evaluating abnormal lesions and lesion sites.

4、 Precautions for using ultrasonic scanners:

1. Operating skills: Doctors need to be familiar with the use of ultrasound scanners and master operating skills to ensure the accuracy and safety of the examination.

2. Patient preparation: Before undergoing an ultrasound examination, the patient needs to remove clothing from the relevant area and maintain comfort and relaxation. For certain special examinations, patients may need to maintain a specific posture.

3. Combined with other examinations: Ultrasonic scanner is widely used as an auxiliary means in the diagnosis of Vascular disease, but in some complex cases, it may be necessary to combine other examination results to make accurate diagnosis.

Conclusion:

Medical ultrasonic scanners are widely used in the diagnosis of Vascular disease, which can help doctors observe and evaluate the structure and function of blood vessels, find lesions and guide treatment. Ultrasonic scanners have the advantages of non-invasive, real-time monitoring, and clear imaging, and have been widely used in clinical practice. However, doctors need to be familiar with the principles and operating techniques of ultrasound scanners when using them, and pay attention to combining other examination results to make accurate diagnoses.
