High resolution computed tomography (CT) was used to determine the normal appearance of the brain of an adult Beagle dog. Objects as small as 0.6 mm for bony structures (high contrast) and 1.5–2.0 mm for soft tissue structures (low contrast) could be resolved in the CT images. Multiplanar imaging using direct transverse and reformatted dorsal and sagittal images made it possible to obtain a three dimensional presentation of anatomy. Selective viewing, where CT number window and level settings were varied, was used to optimize visualization of specific brain structures. Normal high contrast components, cerebrospinal fluid, and osseous land‐marks, were important aids in identification of various intracranial structures. Quantitative densitometry was performed to characterize various regions of the brain in terms of their x‐ray attenuation values or CT numbers. This study indicated that high resolution CT provides a qualitative and quantitative appraisal of the canine brain that is unavailable using conventional radiographic technics.
