Neuroradiological aspects of experimental traumatic missile injury in sheep.

Abstract Radiological assessment of ovine brains subjected to experimental gunshot injury was performed using computed tomography. This imaging procedure enabled precise localisation of the projectile and metal and bony fragments, and depicted parenchymal damage, distortion and displacement of the brain, and skull fractures. Computed tomography scanning was found to be useful in the clinical evaluation of craniocerebral missile injuries and confirmed the acceptability of the 0.22 calibre rifle and 12-gauge shotgun for the euthanasia of sheep.
