title: [Multidetector computed tomography in acute abdomen].
abstract: MDCT has become a fundamental tool for determining the causes of acute abdomen. CT is considered the imaging technique of choice in the diagnostic workup of both localized and diffuse acute abdomen, except in patients in whom acute cholecystitis or acute gynecological disease is suspected and in children, adolescents, and pregnant patients, in whom ultrasonography is the imaging technique of choice. Plain-film X-ray examination has been relegated to the initial management of renal colic, suspected foreign bodies, and intestinal obstruction. One of the drawbacks of MDCT is its use of ionizing radiation, which makes it necessary to filter and direct the examinations as well as to ensure that the most appropriate protocols are used. For this reason, low dose protocols have been developed so that diagnostic studies can be performed with doses of radiation between 2 and 3 mSv; these are normally used in the diagnosis of renal colic and can also be used in selected patients with suspected appendicitis and acute diverticulitis.
