With the universal acceptance of contrast-enhanced computed tomography (CT) as the imaging modality of first resort in the assessment of blunt abdominal injury, the trauma radiologist must be able to accurately and rapidly identify the range of CT manifestations of the traumatized abdomen. In this article, we lay out the fundamental principles in CT interpretation of blunt trauma to the hepatobiliary system and spleen, including vascular injury, with a focus on technical and interpretive pearls and pitfalls. This review will help radiologists and trainees become more familiar with key aspects of abdominal CT trauma protocol selection, CT-based solid organ injury grading, and the various appearances and mimics of hepatobiliary and splenic injury.
