Blunt abdominal trauma is a frequent finding in patients with multiple trauma, and is associated with significant morbidity and mortality. Multislice computed tomography (MSCT), allowing for multiplanar reconstructions and three-dimensional images, has become the imaging modality of choice for these patients. MSCT is indicated in all haemodynamically stable patients with suspected blunt abdominal trauma. A `focussed CT' algorithm, as recommended by the Advanced Trauma Life Support (ATLS®) program, may be useful for patients with isolated abdominal trauma who are conscious and cooperative. For unconscious patients with or without multiple trauma `unfocussed' whole-body MSCT algorithms should be used, as these lead to earlier as well as more accurate diagnosis. MSCT allows for rapid diagnosis of abdominal and retroperitoneal injuries and for grading of solid organ injuries. Active haemorrhage may be detected with accuracy similar to angiography. Even bowel, diaphragmatic and bladder injuries, where CT used to miss a significant number of injuries, can be diagnosed with high accuracy by the new generation of MSCT scanners.
