Ultrasound is able to detect uterine problems. Ultrasound can detect abnormalities in the shape of the uterus, the size of the uterus, adenomyosis, fibroids, as well as uterine polyps or abnormal endometrial growths. In addition, ultrasound can also detect ovarian cysts or adnexal problems, making ultrasound an effective initial diagnostic tool for most gynecological problems. The principle of ultrasound is to understand the corresponding situation through ultrasound reflection, because different tissues of the human body will have different acoustic characteristics, and in different tissue interfaces will also produce reflective echoes, so as to initially determine whether they have organ problems. ultrasound examination has no limitations, and almost anyone can do it, so ultrasound examination in gynecology is a very common item. Ultrasound can be performed for both physical and gynecological tests, and it is recommended that women have it done 1 to 2 times a year to better understand their own situation.
