Ovarian cysts can be detected by ultrasound. Ultrasound is one of the most basic examinations in obstetrics and gynecology, and it is possible to observe some conditions of the uterine adnexa, including the presence of abnormalities on the ovaries, such as ovarian cysts, the size and nature of which can be accurately distinguished by ultrasound. It is more accurate than abdominal ultrasound and is recommended for women who are sexually active and undergo gynecological checkups to observe the uterus and adnexa for initial screening.
