Evaluation of bowel and mesenteric blunt trauma with multidetector CT: spectrum of signs beyond pneumoperitoneum

Abstract

Multidetector computed tomography (CT) is the primary imaging modality for diagnosing bowel and mesenteric blunt trauma. Pneumoperitoneum is the commonly observed for imaging sign among radiologists. There are, however, other CT findings with different clinical significances. The aim of this article is to heighten radiologist awareness regarding the diagnostic capability of CT in bowel and mesenteric blunt trauma, and to illuminate potential pitfalls to be avoided in this patient population. This guide was developed to enhance the knowledge and awareness of non-expert radiologists that may be less aware of the nuances of abdominal CT imaging in a blunt trauma setting. This enhanced knowledge and awareness will improve patient diagnosis, treatment, and outcomes.
