[Evidence-based diagnosis of abdominal trauma]

Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a "focused assessment with sonography for trauma" (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for "wait and see" treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences.
