Endometriosis is one of the common diseases of the Female reproductive system. The earliest description of the disease appeared in the 17th century BC, and its etiology and treatment are still controversial. In clinical diagnosis, ultrasound diagnosis of Endometriosis has been widely used. This article will introduce the technical principle, application and progress of ultrasonic diagnosis of Endometriosis, in order to help readers better understand the diagnostic methods of the disease.

1、 Technical Principles

Endometriosis is a disease that can only be diagnosed by endoscopic surgery, but surgery has the limitations of trauma, high cost, and difficult to repeat. Therefore, ultrasound diagnosis has become a non-invasive, economical, and reusable cutting-edge diagnostic technology. Ultrasonography is based on the working principle of ultrasound and relies on the transmission of ultrasound to obtain some physical sign information from the inside of the human body to determine the existence and location of Endometriosis. Here are the specific technical principles:

1. Physical principle of ultrasonic wave: ultrasonic wave is a Mechanical wave whose frequency exceeds the limit of human hearing. It is emitted into the human body by simulating high-frequency vibration. Therefore, the propagation speed of ultrasound in different tissues and organs also varies, and the displacement of the response also varies, which can achieve the shooting and judgment of different physical sign information.

2. Ultrasonic image of Endometriosis: In ultrasonic examination, a vaginal probe is usually used, and the probe is placed inside the female vagina. During the detection, the image of the vagina similar to the male prostate can be seen on the screen, which is used to determine the existence and degree of Endometriosis at different stages.

3. Diagnostic criteria of ultrasound: ultrasound has certain criteria for the diagnosis of Endometriosis, including the location, shape and size of the ectopic focus. Among them, the location of the ectopic focus should be perpendicular to the cervix, with high visibility; The shape of the ectopic focus should be relatively uniform, with a dark dot like color; The size of the ectopic lesion should be at least 2mm and compared with the size of the anterior and posterior fornix to distinguish whether there is an ectopic lesion.

2、 Application and Progress

In clinical application, ultrasonic diagnosis has become one of the important diagnostic methods of Endometriosis. Mainly based on its non traumatic and non radiation characteristics, it is an efficient and safe diagnostic tool used in clinical practice. Its application scope covers the whole diagnosis field of Endometriosis, mainly including the following aspects:

1. Early diagnosis is needed for the initial Endometriosis. In this case, ultrasound examination can clearly diagnose and facilitate early treatment.

2. For the regular examination of Endometriosis, ultrasound can help doctors carry out physical examination very conveniently, which is very meaningful for disease monitoring, treatment and follow-up.

3. Ultrasonic examination is of great value and significance in investigating and confirming the suspected cases of Endometriosis, which can filter out the possibility of other diseases besides the suspected cases.

Although ultrasonic examination has good reliability for the diagnosis of Endometriosis, its results are closely related to the experience and skills of operators. Therefore, with the development of technology, automated ultrasound examinations have begun to be explored and applied. This method not only reduces the interference of human factors, but also effectively improves the accuracy and speed of diagnosis, which is worth further research and exploration.

3、 Summary

The ultrasonic diagnosis technology of Endometriosis has become an indispensable part in the diagnosis of complex diseases in medicine, and has been widely used because of its advantages of non-invasive, non radiation, high accuracy and so on. It is necessary to pay attention to and master the technical principles and standards of ultrasound diagnosis in application and progress, in order to better improve the efficiency and reliability of examination. In the future, the application of automated ultrasound technology will provide more assistance for the development of diagnosis and treatment of Endometriosis.
