RESUMOPara o presente trabalho, foi realizado um levantamento bibliográfico abordando os métodos diagnósticos da hérnia discal, a qual é a discopatia mais comum em cães e está relacionada aos distúrbios neurológicos que envolvem a medula espinhal. A hérnia discal é a principal causa para a investigação imagenológica da coluna vertebral em pequenos animais. O diagnóstico por imagem é fundamental para obter o conhecimento da doença, da localidade da lesão e da gravidade. Os exames mais comuns realizados na rotina veterinária são a radiografia e a mielografia, por serem mais acessíveis, porém o diagnóstico preciso se dá por meio da tomografia computadorizada ou da ressonância magnética, sendo esta última a técnica primordial para as discopatias. Esses fatores, bem como sua etiologia, fisiopatologia e predisposição serão abordados também neste estudo.Palavras-chave: disco intervertebral, radiografia, tomografia computadorizada, ressonância magnética IMAGING DIAGNOSTIC OF HANSEN TYPE I, II AND III DISC HERNIATION IN DOGS ABSTRACTFor the present study was reviewed bibliography about the diagnostic methods of disc herniation, which it is the discopathy most common in dogs and it is related to neurological disorders involving the spinal cord. Disc herniation is the main cause for the imaging investigation of the spine in small animal. Diagnostic imaging is fundamental to have knowledge of the disease, the location and severity of the lesion. The most common examinations performed in veterinary medicine are radiography and myelography, because they are more accessible, but an accurate diagnosis is made through computed tomography or magnetic resonance, being the latter the primary technique to the discopathy. These factors, as well as the etiology and pathophysiology will be approached also in this study. DIAGNÓSTICO POR IMAGEN DE LA HERNIA DISCAL HANSEN TIPO I, II Y III EN LOS PERROS RESUMENPara este estudio, se realizó una literatura sobre los métodos de diagnóstico de la hernia de disco, que es la enfermedad del disco más común en los perros y se relaciona con trastornos neurológicos que implican la médula espinal. La hernia de disco es la causa principal para la investigación por imagen de la columna vertebral en los animales pequeños. El diagnóstico Recebido em: Aceito em:
The giant anteater (Myrmecophaga tridactyla) is the largest of the Neotropical vermilinguans. This animal is the second mammal most frequently run over on the roads of Cerrado biome, Brazil. Therefore, it is pivotal to know the anatomy of this species to contribute to the clinical care of these animals. Thus, the aim of this study was to identify the anatomical structures in the abdominal region of the giant anteater using computed tomography (CT). For this, the tomographic analysis was performed in sequential order in the craniocaudal direction in five giant anteaters. Moreover, four giant anteater corpses were used for anatomical studies, where two corpses were sectioned in cross sections of approximately 3 cm each, and two animals were dissected to identify the abdominal organs. The association between CT and anatomical study allowed the visualization of anatomical structures found in the abdominal cavity, such as the topographic anatomy facilitates the identification of organs on CT images. The findings of this study demonstrated that CT is a good technique to provide detailed information about the anatomical structures in the abdominal cavity and that this study can be used as CT and anatomical reference for veterinarians who care for wild animals.
