Case Study: CT - Front nasal fracture
This canine patient was run over by a car and unfortunately sustained multiple severe injuries and bone fractures at a number of sites. One such fracture was to his skull, and there was concern that it may have included some of the vital support structures around his eye, or even the bony casing around his brain. CT scanning allows the best evaluation of complicated fractures, or where overlying structures make interpretation using conventional X-rays difficult. It does this by taking cross-sectional images through the area of interest slice by slice. This means that there is no superimposition of structures (unlike conventional X-rays), and our advanced post-processing capabilities (where the cross-sectional images are reconstructed by the powerful computer on the CT scanner) allows viewing from multiple angles.
The first CT image shows a single slice through the area of the fracture. The outer bone of the air-filled (black) frontal sinus to the right of the image has collapsed inwards, but the underlying brain is unaffected. The other two images show post-processing 3D reconstruction of the skull with two different views of the compression fracture.
