Low back disease is a common disease, particularly common in the adult population. With the changes in human lifestyles and the trend of aging population, various diseases related to the lower back are becoming major medical and social issues. Ultrasound examination has become one of the important methods for diagnosing low back diseases, which can help doctors quickly and accurately determine the type and degree of the disease, in order to better treat it.

1、 The Basic Principles of Ultrasound Diagnosis of Lumbar and Back Diseases

Ultrasound diagnosis is a technique that uses sound waves to diagnose diseases. When ultrasound propagates in human tissues, it will reflect and scatter with different edges and structures of different densities within the tissue, forming different echo images. The computer generates corresponding medical images based on these images. When ultrasound vertically irradiates the human body, the waist and back are one of the areas with the highest vibration amplitude, so ultrasound examination of the waist and back is a very common medical diagnostic method. Ultrasound examination of the lower back is a non-invasive examination that does not cause any harm to the patient's body.

2、 Application of Ultrasound in Diagnosis of Lumbar and Back Diseases

Ultrasound diagnosis can detect and diagnose various low back diseases, such as scoliosis, sacroiliac arthritis, lumbar disc herniation, and so on. The professional examination and judgment of various waist and back diseases may vary, but when using ultrasound diagnosis for diagnosis, the images we see can clearly show the location, shape, and degree of the disease. For example, when a patient experiences low back pain, ultrasound diagnostic experts can use visual diagnostic techniques to examine the patient's waist and diagnose their disease.

3、 The advantages of ultrasound in diagnosing lower back diseases

Ultrasound diagnosis can provide reliable and fast results. In general, ultrasonic examination takes about 15-20 minutes, and if necessary, more examinations can be completed. In addition, ultrasound has the characteristics of non-invasive and non radioactive, which does not cause any harm to the patient's body and has extremely high safety. Meanwhile, ultrasound diagnosis can provide dynamic scanning effects, displaying and diagnosing tissues such as muscles, tendons, nerves, joints, and spine, greatly reducing the difficulty and cost of medical management.

4、 Limitations of Ultrasound Diagnosis of Lumbar and Back Diseases

The effectiveness of ultrasound diagnosis in obese patients is limited. Ultrasound is reflected and absorbed by tissues when passing through the human body, while obese patients often have a thick layer of fat in their waist, which reduces the penetration and reflection of ultrasound. Therefore, for patients who are excessively obese, other examination methods need to be used for auxiliary diagnosis.

5、 Conclusion

In summary, ultrasound diagnosis is a very practical method for detecting lower back diseases. It provides intuitive and accurate images through visualization technology, reducing the pain and discomfort of patients during the medical process. With the continuous promotion of technological innovation and application, ultrasound diagnosis has increasingly become one of the important means of diagnosing lower back diseases. However, in application, it is also necessary to combine and supplement with other diagnostic methods in order to more accurately diagnose and treat patients' diseases.
