CT scan evaluation of blunt hepatic trauma.

Information provided by CT scan allows for determination of the extent of liver injury and identification of other nonhepatic abdominal injuries. This information, coupled with clinical assessment, can be used to optimize management. Contrast-enhanced CT scan can monitor progression or resolution of hepatic injuries, detect complications, and guide percutaneous treatment of some complications. This article discusses CT scanning technique; classification, sites, and mechanisms of liver injury; CT scan appearance of liver injury; and complications of hepatic trauma.
