Ultrasound examination in women is mainly to see if there are any abnormalities in the uterine adnexa, whether there are fibroids, intermyometrial or subplasmic fibroids in the uterus, and in some cases in more specific areas, such as broad ligament fibroids or cervical fibroids. Another type of lesion is adenomyosis or adenomyoma, which is an ectopic endometrium into the myometrium, and may manifest as an uneven distribution of light spots in the myometrial wall and an anterior or posterior shift of the endometrial line. Some adenomyoma is not very complete and the border is not clear, and may also show dysmenorrhea. Ultrasound examination of women is also to see if there are ovarian cysts on the ovaries, including ordinary cysts and endometriosis cysts, i.e. chocolate cysts, and also to see if there is thickening and thickening of the fallopian tubes and fluid in the fallopian tubes, and also to see if there is pelvic vein stasis syndrome.
