Down syndrome is a congenital disease caused by chromosome abnormalities, which affects the physical and intellectual development. It is reported that one or two children in every 1000 newborns will have Down syndrome, which is more common among Advanced maternal age. The best way to diagnose Down syndrome is through non-invasive prenatal ultrasound screening (NIPT). This article will discuss the technical principle of prenatal ultrasound scanning, the etiology and treatment of Down syndrome, and the impact on maternal and fetal health.

1、 Technical principles of prenatal ultrasound scanning

Prenatal ultrasound scanning is a non-invasive technique for detecting the health status of the fetus. By real-time irradiation of high-energy sound beams, the body structure and organs of developing fetuses can be observed in vitro. Its main function is to scan the temperature of various liquids and soft tissues, greatly improving the accuracy and feedback speed of detecting fetal health. During prenatal ultrasound scanning, doctors measure part of the blood thickness on the neck of the fetus, and check the organs and Skeleton of the fetus.

Prenatal ultrasound scanning can also determine the sex of the fetus, as well as the risk of various diseases, including Down syndrome.

2、 Causes and treatment of Down syndrome

Down syndrome is a congenital disease caused by three copies of Chromosome 21, namely trisomy 21 (three 21 chromosomes). This enables patients with Down syndrome to have lower intelligence and computer design modeling simulation, heart malformation, enlarged tongue and delayed development. Down syndrome patients also develop more slowly in terms of weight and height.

At present, there is no complete cure for Down syndrome, but patients can receive a series of treatment measures to ensure their physical and mental health. These measures include medication treatment, diagnosis, and prevention, as well as adjustments to the social environment.

3、 Prenatal screening for Down syndrome

In the past, the diagnosis of Down syndrome mainly depended on postpartum diagnosis. But this diagnostic method may delay time and cause great distress to patients. Now, prenatal ultrasound scanning technology has been able to screen whether the fetus has signs of Down syndrome, which allows patients to obtain a more reliable Prenatal testing, that is, the diagnosis is at the delivery site (before membrane rupture or artificial delivery).

In the prenatal screening procedure, the doctor will first let the fetus undergo a test for Down syndrome. When the examination results show that the fetus is at risk of Down syndrome, the doctor will recommend further examination to determine whether the fetus is suffering from Down syndrome.

4、 The impact of prenatal ultrasound scanning on maternal and fetal health

Prenatal ultrasound scanning is a non-invasive detection technique that has minimal impact on the health of mothers and infants. On the contrary, prenatal ultrasound scans ensure the health of the fetus and mother by timely diagnosing and predicting the risks they face. However, physicians should only recommend prenatal ultrasound scans in necessary or particularly complex situations, and generally recommend no more than three ultrasound scans.

5、 Conclusion

Prenatal ultrasound scanning is a widely used technology in the field of obstetrics and gynecology. Its advantages of simple operation, non-invasive and being able to detect fetal health make it one of the very important prenatal screening methods, especially for the early diagnosis of Down syndrome. Although the patients with Down syndrome cannot be completely cured at present, they can be initially controlled and protected through early prevention and treatment. In the future, the development of this technology will have a greater impact and guarantee on the health of fetuses and mothers.

The Development History and Application Prospects of Ultrasonic Scanning Technology

With the development of technology, the technology in the medical field has also been greatly improved. Ultrasonic scanning technology is one of the imaging technologies in medicine, which uses the images generated by Super high frequency sound waves to observe the internal structure of the human body. Since the mid-20th century, ultrasound technology has been increasingly applied in medicine, becoming an important technology in modern medicine and an indispensable part of medical diagnosis. This article will introduce the development process and application prospects of ultrasonic scanning technology.

1、 The Development History of Ultrasonic Scanning Technology

Ultrasonic scanning is a technology based on the propagation and reflection laws of sound waves, which was first used in military reconnaissance. Imaging instruments focus imaging through ultrasound, similar to the reflection of water surface waves above a specific underwater point. The imaging instrument converts the rebound point into an image, representing the internal structure of the object. Since the application of ultrasound scanning technology in medicine, it has a long history. In the 1930s, the medical community began researching and observing the condition of the fetus in the uterus of pregnant women. Until the 1950s, Medical imaging subversively entered the stage of ultrasonic imaging.

At this stage, unit waves smaller than 10 MHz generate ultrasound devices specifically designed for medical imaging. In the late 1950s, with the gradual reduction of the cost of ultrasound scanners, ultrasound scanning gradually became widely used as a relatively simple, reliable, and non-invasive medical diagnostic method. In the past decade, the field of ultrasound has also experienced rapid development. Modern ultrasonic scanning technology can achieve higher resolution, and at the same time, the size of ultrasonic imagers is becoming smaller and can be applied to handheld portable ultrasonic scanners.

2、 Application Fields of Ultrasonic Scanning Technology

The application of ultrasound scanning technology in medicine is becoming increasingly widespread, as it is widely used in internal medicine, surgery, and various special medical fields. The following are some of the main applications of ultrasound scanning technology in medicine:

1. Obstetrics

In the field of obstetrics, ultrasound scanning technology has become the gold standard for prenatal examination and fetal monitoring. Ultrasound can detect the growth and development of fetuses in the uterus, and detect some fetal abnormalities, such as intrauterine infections, congenital malformations, placental abnormalities, and so on.

2. Cardiology

In the field of cardiovascular disease, ultrasound scanning technology is a very popular method that can be used to detect heart, cardiovascular problems, blood circulation disorders, and so on. For example, echocardiography is a non-invasive examination that can detect the internal structure of the heart, heart function, etc. It can detect some heart and Vascular disease.

3. Gynaecology

In Gynaecology, ultrasonic scanning technology is often used to evaluate the treatment effect of pelvic organs and several women's diseases. For example, we can explore the mass of Uterine appendages and the static and dynamic signs of cell milk appendages.

4. Cancer identification

In the field of cancer diagnosis, ultrasound scanning technology is also very effective. For certain parts and types of small tumors, X-ray photography and plain CT scanning may not necessarily be able to detect them, while ultrasound scanning technology can effectively detect and detect these abnormalities.

5. Other fields

In addition, ultrasonic scanning technology can also be applied to orthopedics, Neurosurgery, liver disease, kidney disease, digestive system disease, Urinary system disease and so on.

3、 Future Development Trends of Ultrasonic Scanning Technology

With the continuous development of science and technology, ultrasonic scanning technology will also be based on current applications and undergo deeper development and research. In recent years, with the improvement of computer technology and the development of artificial intelligence, high-end ultrasonic equipment has completed deep integration with artificial intelligence, and this technology is believed to be further improved in the near future.

Even in widely used fields, ultrasonic scanning technology still has considerable room for improvement. With the increasingly widespread clinical application, the scanning speed of ultrasound scanning technology will continue to improve, with rock solid accuracy and stronger auxiliary practicality. At the same time, with the rapid advancement of technology in the medical field, future ultrasound devices will be combined with other medical devices, demonstrating their collaborative capabilities in multiple fields.

In short, with the advancement of technology, ultrasound scanning technology will have broader development space, and it has been widely applied in the medical field and will achieve higher value in the future.
