Most cases of endometriosis can be diagnosed by ultrasound, but ultrasound is generally unable to clearly show small lesions that are ectopic to the pelvic peritoneum or vagina.
Endometriosis is a condition in which normal endometrial tissue is born outside of the uterine cavity. It is most common in the ovaries, uterine rectal pit, and uterosacral ligaments, but can also occur in the abdominal cavity, thoracic cavity, and vagina.
B-mode is an important method to diagnose endometriosis, which can determine the location, size and shape of ectopic cysts, and can clearly see endometriotic lesions in the ovaries, vesicorectum and other parts of the uterus; however, ultrasound is usually difficult to see lesions in the pelvic peritoneum, vagina and other parts of the uterus; however, ultrasound is also able to detect the lesions if they enter into the later stages and form obvious thickening locally.
In conclusion, if you suspect endometriosis, you should go to the hospital in time, improve the relevant examination under the guidance of the doctor, and treat it as early as possible.
