Study the incidence, type and outcome of traumatic ischemic arterial lesions of the kidney in multiple trauma patients. ⋯ We found a high incidence of traumatic renal dissection in multiple trauma patients. Multidetector scan appears to provide the best results for the diagnosis of these lesions as well as the many associated lesions resulting in a very poor prognosis for these patients. Treatment is not well defined and management of these lesions is often of secondary importance because of the severity of associated injuries.

Cranial traumas from gunshot wounds are characterised by the impact of a high velocity projectile. There are therefore serious, life threatening traumas. CT Scan is essential in the emergency setting for initial evaluation of traumatic bone and parenchymatous injuries to determine the indication for neurosurgery and appropriate medical management. In case of survival, CT Scan and MRI can be used to monitor progress and any possible complications, in particular vascular or infectious complications which are specific to this type of injury.

The purpose of this article is to provide radiologists with key elements of radiation protection for interventional radiology patients. The following points will be discussed: standards of the fluoroscopy units, dedicated dosimetry, risks (especially cutaneous) and means to reduce them, optimization of interventional radiology dose protocols, and national and international regulations. Appropriateness criteria in interventional radiology are national guidelines that should be implemented.

After a risk analysis has been completed by the radiation safety officer, all entities where a source of ionizing radiation is present must established a monitored or controlled zone containing the source. When exposure exceeds the maximum regulatory dose, a dedicated color-coded controlled (yellow or orange) or restricted zone must be established. All assessments performed by the RSO should reflect normal working conditions. ⋯ The workers should undergo medical and dosimetric follow-up with the use of passive dosimetry. The use of operational dosimetry should be added when working in a controlled zone. A radiation dosimetry report for each worker should be available to the occupational medicine provider to ensure appropriate dosimetric monitoring.
