Patients with severe polytrauma: management and imaging protocols

Traumatic injuries can be severe and complex, requiring the coordinated efforts of a multidisciplinary team. Imaging tests play a fundamental role in rapid and accurate diagnosis. In particular, whole-body computed tomography (CT) has become a key tool. There are different CT protocols depending on the patient's condition; whereas dose-optimized protocols can be used in stable patients, time/precision protocols prioritizing speed at the cost of delivering higher doses of radiation should be used in more severe patients. In unstable patients who cannot be examined by CT, X-rays of the chest and pelvis and FAST or e-FAST ultrasound studies, although less sensitive than CT, enable the detection of situations that require immediate treatment. This article reviews the imaging techniques and CT protocols for the initial hospital workup for patients with multiple trauma.
