A transverse CT image through an equine head. The nasal cavities and para-nasal sinuses should be symmetric. In this case a large, round, soft tissue attenuating mass is present in the rostral maxillary sinus, consistent with an ethmoid hematoma. (arrow) ~ Select for larger image

Computed tomography provides multiple, sequential slices through the area of interest in any plane. In this example several transverse slices through the carpus show comminuted fractures of multiple carpal bones. The bottom image shows a comminuted fracture through the fourth carpal bone; this fracture was seen as mild lateral displacement of this bone on radiographs (red arrows). While the top two images show the proximal row of carpal bones and fracture of the intermediate carpal bone that was not visible on plane radiographs.  ~ Select for larger image
