RESUMENEl objetivo de este estudio fue proporcionar una descripción detallada de la anatomía normal del cerebro de potrillos neonatos y de las estructuras asociadas mediante tomografía computarizada (TC) y cortes anatómicos. Se utilizó un escáner de cuarta generación y se adquirieron imágenes transversales con un grosor de dos milímetros. Tras el estudio por TC, los animales fueron sacrificados por razones no relacionadas con patologías de la cabeza. Para ayudar en la identificación precisa del cerebro y las estructuras asociadas, las imágenes de TC fueron comparadas con las correspondientes secciones de la cabeza. Las imágenes de TC se correlacionaron de buena manera con sus correspondientes secciones anatómicas, mostrando una buena diferenciación entre el tejido óseo y el tejido blando de la cabeza. Las imágenes obtenidas mediante TC pretenden ser una referencia anatómica inicial para la interpretación de los estudios clínicos del cerebro y las estructuras asociadas en potros vivos recién nacidos.Palabras clave: tomografía computarizada, anatomía, cerebro, potro neonato. SUMMARYThe aim of this study was to provide a more complete description of normal cross-sectional anatomy of the neonatal brain of the foal and associated structures by computed tomography (CT) and gross anatomical sections. Using a fourth-generation CT scanner, 2-mm contiguous transverse images were acquired from two neonatal 5-days-old Quarter horse foals. After the study the animals were euthanised for reasons unrelated to head pathology. To assist in the accurate identification of brain and associated structures, transverse CT images were obtained and compared with the corresponding frozen cross-sections of the head. CT images matched well with their corresponding transverse gross sections and provided good differentiation between the bones and the soft tissues of the head. These CT images are intended to be a useful initial anatomic reference in the interpretation for clinical CT imaging studies of the brain and associated structures in live neonatal foals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
