1. Apply the American Association for the Surgery of Trauma-Organ Injury Scale (AAST) to grade hepatic injuries utilizing MDCT  2. Discuss the role of MDCT in the detection of hepatic injury and active bleeding 3. Distinguish false (+) MDCT findings from true hepatic injuries to avoid misdiagnosis   

MDCT is the imaging modality of choice for evaluation of hemodynamically stable patients with abdominal blunt trauma. The liver is the second most common injured abdominal solid organ, and the most frequent abdominal injury resulting in death. A retrospective collection of patients with blunt abdominal trauma from our level I trauma center are included in this pictorial essay. Hepatic lesions are described and classified following the American Association for the Surgery of Trauma-Organ Injury Scale (AAST). The following MDCT imaging finding are presented and discussed: a. Hematoma (subcapsular or intraparenchymal) b. Laceration c. Shattered liver d. Hilar vascular injury. The usefulness of arterial acquisition for detection of active bleeding. e. The delayed hepatic rupture process is reviewed. This exhibit reinforces the comprehensive valve of MDCT in the diagnosis and grading of blunt hepatic trauma, and the impact of imaging on patient management. Mimics should be recognized to avoid unnecessary invasive procedures.
