Angiografia cerebral é o método de imagem empregado para detecção de alterações dos vasos sanguíneos do cérebro, pela injeção de contraste positivo e obtenção da imagem por meio da radiografia convencional, tomografia computadorizada ou ressonância magnética. No presente trabalho, descreve-se a técnica com o emprego da radiografia convencional em razão da disponibilidade muito restrita de equipamentos de tomografia computadorizada e da inexistência de equipamentos de ressonância magnética na área da medicina veterinária, no Brasil. O objetivo foi avaliar a eficácia do meio de imagem para demonstrar o padrão angiográfico de animais sem afecção neurológica, visando a preencher a lacuna deixada pelo exame radiográfico simples, em casos de alterações de fluxo sanguíneo intracranianos. Concluiu-se que a técnica utilizada é eficaz para a obtenção de imagens nítidas dos vasos cerebrais e sua distribuição.Cerebral angiography is an imaging technique used to detect alterations in the blood supply of the brain. A positive contrast is injected and the image obtained by conventional radiography, computerized tomography or magnetic resonance (MRI). The present research describes the technique with the use of conventional radiography due to the rare availability of tomography or MRI equipment in veterinary practice. The objective was to evaluate the efficiency of the method in demonstrating the angiographic pattern of normal animals, to serve as a complementary exam to simple x-ray and improve the capability of detecting altered intracranial blood flow. It is concluded that the technique is capable of producing clear images of cerebral vessels and its ramifications.
