Routes

The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically designed vaginal transducer. Transvaginal imaging utilizes a higher frequency imaging, which gives better resolution of the ovaries, uterus and

endometrium The endometrium is the inner epithelium, epithelial layer, along with its mucous membrane, of the mammalian uterus. It has a basal layer and a functional layer: the basal layer contains stem cells which regenerate the functional layer. The funct ...

(the fallopian tubes are generally not seen unless distended), but is limited to depth of image penetration, whereas larger lesions reaching into the abdomen are better seen transabdominally. Having a full bladder for the transabdominal portion of the exam is helpful because sound travels through fluid with less attenuation to better visualize the uterus and ovaries which lies posteriorly to the bladder. The procedure is by definition invasive when performed transvaginally. Scans are performed by health care professionals called sonographers, or gynecologists trained in ultrasound.

Applications

Gynecologic sonography is used extensively: * to assess pelvic organs, * to diagnose

acute appendicitis Appendicitis is inflammation of the appendix. Symptoms commonly include right lower abdominal pain, nausea, vomiting, fever and decreased appetite. However, approximately 40% of people do not have these typical symptoms. Severe complications o ...

* to diagnose and manage gynecologic problems including

endometriosis Endometriosis is a disease in which Tissue (biology), tissue similar to the endometrium, the lining of the uterus, grows in other places in the body, outside the uterus. It occurs in women and a limited number of other female mammals. Endomet ...

, leiomyoma, adenomyosis, ovarian cysts and lesions, * to identify adnexal masses, including ectopic pregnancy, * to diagnose gynecologic cancer * in infertility treatments to track the response of

ovarian follicle An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It secretes hormones that influence stages of the menstrual cycle. In humans, women have approximately 200,000 to 300,000 follicles at the time of puberty, ea ...

s to fertility medication (i.e. Pergonal). However, it often underestimates the true ovarian volume. Through transvaginal sonography ovarian cysts can be aspirated. This technique is also used in transvaginal oocyte retrieval to obtain human eggs (

oocyte An oocyte (, oöcyte, or ovocyte) is a female gametocyte or germ cell involved in reproduction. In other words, it is an immature ovum, or egg cell. An oocyte is produced in a female fetus in the ovary during female gametogenesis. The female ger ...

s) through sonographic directed transvaginal puncture of ovarian follicles in IVF. Gynecologic ultrasonography is sometimes overused when it is used to screen for ovarian cancer in women who are not at risk for this cancer., which cites * * * * There is consensus that women with only average risk for ovarian cancer should not be screened with this procedure for cancer.

Sonohysterography

Sonohysterography is a specialized procedure by which fluid, usually sterile saline (then called saline infusion sonography or SIS), is instilled into the uterine cavity, and gynecologic sonography performed at the same time. A review in 2015 came to the conclusion that SIS is highly sensitive in the detection of intrauterine abnormalities in subfertile women, comparable to hysteroscopy. SIS is highly sensitive and specific test in the diagnosis of uterine polyps, submucous uterine fibroids, uterine anomalies and intrauterine adhesions (as part of Asherman's syndrome), and can be used as a screening tool for subfertile women prior to IVF treatment.
