SUMMARY:The use of advanced imaging in diagnostic patient evaluations is increasing as well as the availability of machines for veterinary practices. The purpose of this study was to provide an atlas of synchronized normal computed tomography and cross sectional anatomy of the metacarpus and digits in the one-humped camel and Egyptian water buffalo to provide a basis for diagnosis of their diseases by the aid of CT. One cm contiguous transverse CT images and cross sectional anatomy were obtained and photographed. Clinically applicable anatomic structures were identified and labeled at each level. In both animals, the medullary cavity of the fused third and fourth metacarpal bones was divided internally by a vertical bony septum which was a complete septum in the camel, complete at the proximal and distal extremities in the buffalo and small and incomplete in main part of fused shaft of metacarpal bones in buffalo. The CT of the present study in both camel and buffalo showed the adjacent extensor tendons as transverse narrow strap with undifferentiated outlines on the dorsal aspect of fused metacarpal bones, proximal phalanges and middle phalanges and the adjacent flexor tendons as roughly rounded mass with undifferentiated outlines on the palmar aspect of fused metacarpal bones, proximal phalanges and middle phalanges. The undifferentiated outlines of the adjacent extensor or flexor tendons in CT images is equivalent to cross sectional anatomy without dissection of the intervening fascia, where the outlines didn't appear in the latter also. Therefore, the cross sectional anatomy is superior to CT only when the intervening fascia is dissected. CT images of the current study have the potential to become part of our standard diagnostic investigation for anatomic regions previously difficult to be evaluated in the camel and buffalo.

“…Entretanto, é crescente o número de estudos com esses animais, o que tem contribuído para um melhor conhecimento da anatomia e fisiologia das espécies, auxiliando, assim, os clínicos e cirurgiões quanto ao diagnóstico definitivo, ao prognóstico e à definição da melhor terapia (Mackey et al, 2008). Nesse processo de desenvolvimento, as técnicas de diagnóstico por imagem, como radiografia, ultrassonografia, tomografia computadorizada e ressonância magnética, têm sido utilizadas na complementação do exame clínico (Valente, 2007).…”

“…O exame radiográfico, indubitavelmente, é uma importante ferramenta para auxiliar o médico veterinário no diagnóstico e na pesquisa de várias enfermidades, visto que sua relação custo-benefício o torna a primeira escolha como método complementar de diagnóstico por imagem (Pinto, 2007). Porém, em algumas classes taxonômicas, como a dos répteis, que não possuem gordura mesentérica, a interpretação e a visibilização de órgãos da cavidade celomática no exame radiográfico ficam limitadas, uma vez que, devido à redução do contraste entre os tecidos, a cavidade é visibilizada como uma estrutura única (Mitchell, 2009). …”

“…A ultrassonografia e a radiografia são modalidades de imagem que fazem parte da rotina clínica, enquanto novas técnicas, como a tomografia computadorizada (TC), a ressonância magnética (RM) e a cintilografia nuclear, são utilizadas com menor frequência (Mackey et al, 2008) em razão do alto custo e da disponibilidade dos aparelhos. Atualmente, a TC está cada vez mais difundida e utilizada na rotina como uma técnica não invasiva e de curta duração (Gumpenberger e Henninger, 2001;Mackey et al, 2008), devido à maior acessibilidade e à diminuição do custo do exame. Ao se analisarem as alterações observadas no exame radiográfico em cada sistema para cada classe, as alterações mais encontradas em mamíferos foram as fraturas de tíbia (11/ 74) e fêmur (9/74).…”

“…La mise en place de structures vétérinaires spécialisées, notamment les Centres Hospitaliers Vétérinaires, permet aux praticiens d'avoir accès à des examens complémentaires de qualité et sophistiqués (Mackey et al, 2008). Parmi ceux-ci, la tomodensitométrie occupe une place de choix en apportant un plus considérable par rapport à l'imagerie conventionnelle et le lapin de compagnie trouve toute sa place dans ses indications (Fischett, 2012).…”

(Communication présentée le 07 février 2013)Cet article décrit la réalisation pratique de l'examen tomodensitométrique chez le lapin de compagnie. Les principales indications sont représentées par les affections buccodentaires, les rhinites récur-rentes, le syndrome vestibulaire, les lésions vertébrales et les lésions intra thoraciques qui représen-tent les affections les plus souvent rencontrées dans cette espèce. Cet examen présente l'avantage d'être non invasif et de fournir des images en désuperpostion, très précieuses notamment dans les affections buccodentaires. La lourdeur de l'investissement et le coût de l'examen représentent cependant les principaux facteurs limitants.
