RESUMEN
This pictorial essay shows low-dose multi-detector computed tomography (MDCT) findings of blunt hepatobiliary trauma, and describes the indications and protocol for MDCT. Given the universal usage of MDCT in assessing the liver in blunt abdominal trauma, reduction of patient dose is essential. The new l0se MDCT protocol presented here can achieve up to 50% dose reduction while maintaining diagnostic image quality and thus facilitate dose sensitive patient management. Our institution's blunt hepatobiliary MDCT imaging algorithm can help determine which patients require operative therapy. Injury to the liver is graded on various schemes, one being the Organ Injury Scale devised by the American Association for the Surgery of Trauma classification based on the extension of the lesion and bleeding.

Nail-gun injury is commonly encountered in the emergency department. The severity of the injury depends on the specific injuries to organs and vascular structures. Computed tomography (CT) is the ideal imaging test of choice, as it can identify the more critical injuries that require immediate intervention. We present a case of self-inflicted nail-gun injury with intracranial and intracardiac nails that was optimally evaluated with CT. CT significantly changed the patient's management, giving priority to potentially life-threatening penetrating cardiac injuries.
