Imaging in abdominal trauma

Prompt recognition and timely intervention both play a crucial role in managing patients with blunt abdominal trauma. In most cases of multiply injured patients, where physical examination is indeterminate, a rapid and accurate screening method is a valuable adjunct for care-providers. Through the years, different imaging techniques have been utilized for this purpose; among them are diagnostic peritoneal lavage (DPL), ultrasonography (US) and computed tomography (CT). Proponents of each modality have their own beneficial reasons for adopting that particular method of imaging. Needless to say, despite the high sensitivity and specificity values cited for each, all the methods have their own limitations. After having reviewed the advantages and disadvantages of these three modalities, this article suggests that there is not one single modality that is considered the best. Rather, all three can be complementary and the use of each can be appropriate for a particular subset of patients, given a particular clinical situation, and taking into account the resources available.
