A prior acquisition without intravenous contrast is recommended. It assesses solid organ hematomas and sentinel hematoma. Arterial acquisition is performed when chest exploration is indicated. Delayed acquisition (2-3 minutes) is performed when renal lesions or active bleeding are diagnosed. A number of studies have evaluated the safety and sensitivity of the triple-contrast CT approach. A metaanalysis performed by Goodman and al. [4], performed to determine the predictive value of CT for laparotomy in hemodynamically stable patients with penetrating abdominal trauma. They identified 180 studies but included only 5 because of methodologic concerns. The pooled sensitivity, specificity, negative predictive value,.
