title: Periportal tracking in hepatic trauma: CT features.
abstract: In retrospective review, 51 cases of hepatic trauma were analyzed for type and location of injury. More than half of these cases (62%) demonstrated periportal zones of decreased attenuation, which is presumed to represent blood in the periportal region. This finding has been termed "periportal tracking" and may be an important sign of subtle liver injury.
