This medical imaging technique is used to display [[muscle]]s, [[tendon]]s, and other internal organs. It makes it easier to assess damage done to these structures. Diagnostic sonography has a wide field of use, including [[emergency medicine]], where it is regularly performed on patients which are in a state of [[Shock (circulatory)|shock]] or [[trauma]]. This test is known as [[Focused Assessment with Sonography for Trauma]]. It can detect any fluid in the body cavities. Doctors can then decide whether life-saving surgery must be performed. == Obstetric sonography == Is the name for a number of tests done during the [[pregnancy]] of a woman. '''Gynecologic ultrasonography''' or '''gynecologic sonography''' refers to the application of medical ultrasonography to the female [[Pelvis|pelvic]] [[Organ system|organs]] (specifically the [[uterus]], the [[ovaries]], and the [[fallopian tubes]]) as well as the [[Urinary bladder|bladder]], the [[Adnexa of uterus|adnexa]], and the [[recto-uterine pouch]]. Gynecologic sonography is used often and throughout many different tests: * to assess [[Pelvic organ|pelvic organs]], * to diagnose [[acute appendicitis]]<ref>{{Cite journal | last1 = Caspi | first1 = B. | last2 = Zbar | first2 = AP. | last3 = Mavor | first3 = E. | last4 = Hagay | first4 = Z. | last5 = Appelman | first5 = Z. | title = The contribution of transvaginal ultrasound in the diagnosis of acute appendicitis: an observational study. | journal = Ultrasound Obstet Gynecol | volume = 21 | issue = 3 | pages = 273–6 |date=Mar 2003 | doi = 10.1002/uog.72 | pmid = 12666223 | s2cid = 39843514 | doi-access = free }}</ref> *
