Summary

Head trauma is a frequent reason for consultation in the emergency room. The CT scan is the reference examination allowing rapid management of the patient. However, CT examinations are among the diagnostic examinations with the highest exposure to ionizing radiation. The study investigators have previously implemented "ultra-low dose" (ULD) acquisitions for several pathologies with an effective dose level similar to that of a standard radiographic examination. These ULD acquisitions are now routinely used in our clinical practice for explorations of the thorax, spine, pelvis and proximal femurs, extremities.

This study expands these ULD acquisitions to skull CT for detecting traumatic intracranial lesions.

The study investigators hypothesize that it would be possible to search for intracranial lesions in patients with head trauma using ULD protocols, thereby reducing the doses delivered to the patient while maintaining sufficient image quality for the diagnosis.
