Computed tomography of the brain is necessary as part of the diagnosis of lesions of the central nervous system, however, is a restricted exam, since it is a relatively recent technique, especially in veterinary medicine in Brazil.In this study we used six domestic cats, males or females aged between one and five years, who came to the Veterinary Hospital of UNESP Jaboticabal for Computed Tomography (CT) examination without clinical signs of central nervous system disorders. Two animals euthanized stating condition unrelated to the nervous system were incorporated into this study. The proposal consisted in establishing detailed anatomical description of tomographic images of normal brain of cats, using as reference anatomical images of cross sections of the stained brain and cranial part, with thicknesses similar to the planes of the CT images. CT examinations were performed with and without intravenous iodinated contrast media for live animals. With one euthanized animal, the brain was removed and immediately preserved in 10% formalin for later achievement in cross-sectional thickness of approximately 4mm and staining technique of Barnard, and Robert Brown. The head of another animal was disarticulated in Atlanto-occipital region and frozen at -20ºC. Then sliced with thickness of about 5mm. The description of visualized anatomical structures using tomography is useful as a guide and allows transcribing with relative accuracy the brain region affected by an injury, and thus correlating it with the clinical symptoms of the patient, providing additional information and consequent improvement to veterinarians during the course of surgical clinic to this species
