Ultrasound examinations can only determine some gynecological diseases. When performing ultrasound examinations, it is important to focus on gynecological ultrasound, i.e. pelvic ultrasound, which can determine whether there is any exudate in the pelvis, whether there is chronic pelvic inflammatory disease through inflammatory exudate, whether there are ovarian cysts in the ovaries bilaterally, whether there are fibroids in the uterus, and whether there is any abnormality in the morphology of the uterus. For example, the presence of endometrial polyps or cervical diseases such as cervical nuchal cysts can be determined by abdominal ultrasound or vaginal ultrasound. However, the presence of vaginal inflammation or cervical inflammation, or human papillomavirus of the cervix, can only be determined in detail by secretion and cytologic examination.
