Color ultrasound is one of the more conventional examination methods at this stage, mainly through two-dimensional ultrasound combined with Doppler blood flow to scan and analyze the examination area to make a correct diagnosis. Gynecological ultrasound is mainly for the examination of female reproductive organs, including the cervix, fallopian tubes, ovaries, pelvis, uterine body, endometrium and other parts. Gynecological ultrasound can clearly determine whether there are tumors in the cervix and whether there is hypertrophy in the cervix. It can also clearly see if there is blockage or fluid in the fallopian tubes. The ovaries can be specifically measured under ultrasound to see if the follicles are developing and discharging normally, and to clearly diagnose if there are cysts in the ovaries. The pelvis is mainly to see if there is fluid in the pelvis, if there is more fluid in the pelvis, it is an indicator of pelvic inflammatory disease. The body of the uterus is mainly to look at the size of the uterus, whether there is dysplasia or malformation, and whether there are fibroids or adenomyomas can also be clearly diagnosed. The endometrium can also clearly show how thick it is, whether the echogenicity is uniform, and whether there are endometrial polyps and many other conditions can be checked. Therefore, gynecological ultrasound is a powerful assistant to help clinicians diagnose gynecological diseases at this stage, and there is no pain or injury to patients during the process of ultrasound, and the examination results are relatively accurate.
