Adult dog: CT‐scan and reconstruction of an osseous cranium (LB9)

Abstract

The osseous cranium of a dog of unknown age and race had been systematically CT‐scanned in the frontal plane. The cranium was laid on the apparatus’ table, its longitudinal axis aligned with the table’s one and the orbito‐meatal plane parallel to the plane’s table. The length of the cranium was 18,5 cm. Several reconstructions were obtained from the native crosss‐sections with an average density. The cross‐sections in the three planes : frontal, para‐sagittal and horizontal ones were reconstructed from the frontal, native cross‐sections using an high resolution with a thickness of 0,75 mm and an interval of 0,6 mm. 308 frontal, 170 para‐sagittal, and 125 horizontal cross‐sections were analyzed. The seriated CT‐scan of an entire cranium in the dog, in the three planes of the space gave great possiblities of analysis in all the kind of bones, for the architectural rendering, their volumes and relationships. This method is now unvaluable in the morphological analysis of the complicated, osseous structures.
