The main gynecological diseases that can be detected by ultrasound are malformation of reproductive organs, gynecological inflammation, gynecological tumors, and other gynecological diseases. 1. Abnormalities of reproductive organs: ultrasound can check the shape, size and position of uterus, fallopian tube and ovary, etc. If there are abnormalities of reproductive organs such as longitudinal uterus, unicornuate uterus, undeveloped or underdeveloped uterus, and tubal underdevelopment, the abnormalities can be detected through ultrasound. 2. Gynecological inflammation: Inflammation of the pelvis and cervix such as tubal effusion, cervical natriuretic cysts, ovarian cysts, etc. can be examined by ultrasound. 3. Gynecological tumors: ultrasound can examine tumors of reproductive organs, such as uterine fibroids, fallopian tube and ovary tumors, and check the size, location, and boundary with surrounding tissues of the tumors, so as to initially assess the benignness or malignancy of the tumors. 4. Other gynecological diseases: such as hyperemesis gravidarum, endometriosis, adenomyosis, etc., can be diagnosed by the unique performance of ultrasound. Gynecological ultrasound is an important auxiliary examination for checking gynecological diseases and can be used for the diagnosis of many gynecological diseases. Depending on the situation, you can choose either transvaginal ultrasound or transabdominal ultrasound, which requires you to hold your urine for the examination. It is recommended to follow the doctor’s advice to do the examination program that suits your condition.
