Description
Summary:Pulmonary function evaluation in dogs can be gotten by scintigraphy exams, which are obtained with radiopharmacs injections, followed by radiography. In this study it was used 10 healthful male dogs of Rottweiler breed, radiographically normal and serum negative for dirofilariasis, with administration of varied doses of human serum albumin grouped marked with technetium-99m (MAA). The results were evaluated qualitatively and quantitatively, considering the index of pulmonary perfusion and its homogeneity, being found an increase on the homogeneity of image directly related with the number of MAA particles injected. This study defines the criteria of normality and the dosage of pulmonary perfusion in healthful dogs established with scintigraphy technique. Key words: pulmonary scintigraphy, dogs, nuclear medicine, Technetium-99m. A avaliacao da funcao pulmonar em caes pode ser obtida mediante exames cintilograficos, os quais incluem a injecao de radiofarmacos, seguida de radiografias. Neste estudo, foram utilizados 10 caes machos higidos da raca Rottweiler e radiograficamente normais e soronegativos para dirofilariose, com administracao de doses variadas de macroagregado de albumina serica humana marcados com tecnecio-99m ([[sup.99m]Tc](MAA)). Os resultados foram avaliados qualitativa e quantitativamente, considerando o indice de perfusao pulmonar e sua homogeneidade, sendo dessa maneira visualizado um aumento na homogeneidade da imagem diretamente relacionado ao numero de particulas de MAA injetado. Este estudo define os criterios de normalidade e de dosagem na perfusao pulmonar em caes higidos da raca rottweiller estabelecidos com a tecnica de cintilografia. Palavras-chave: cintilografia pulmonar, caes, medicina nuclear, Tecnecio-99m.
