Summary

The conventional standard-dose scanner leads to a significantly greater X-ray exposure than the standard X-ray. Recently, technological innovations like the ULD ("Ultra Low Dose") scanner have been developed to reduce the dose of X-rays delivered to the patient. The general purpose of this study is to validate the ULD scanner in case of emergency trauma of the dorsolumbar spine, pelvis and / or extremities.

Conditions

  • Bone Fractures

Interventions

DIAGNOSTIC_TEST

Patient undergoes a ULD scan

The following doses will be applied: 6 mGy.cm for the extremities 50 mGy.cm for the dorsal spine 130 mGy.cm for the lumbar spine 130 mGy.cm for the pelvis

DIAGNOSTIC_TEST

Patient undergoes a standard X-ray

The following doses will be applied: For the pelvis : front view and profile for the hip. For the dorsal spine : front and profile. For the lumbar spine : front and profile For the extremities : front and profile

DIAGNOSTIC_TEST

Patient undergoes a classic-dose scan

The following doses will be applied: 6 mGy.cm for the extremities 50 mGy.cm for the dorsal spine 130 mGy.cm for the lumbar spine 130 mGy.cm for the pelvis
