Computed tomographic imaging of the brain of normal neonatal foals

Abstract

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.

Cone-beam computed tomography of the head in standing equids

“…Computed tomography (CT) has become an important imaging modality for the diagnosis of diverse head disorders in the horse [1–6]. The cross-sectional imaging modality provides images of nasal and paranasal passages, the teeth, skull bones, the hyoid apparatus, and the teeth without superimposition and allows 3-dimensional reconstruction [7].…”

“…The use of contrasted techniques may be an important adjunct to anatomical studies through imaging diagnostics because they offer more advantages when used in living animals; they present greater dispersion due to the pressure and flow of the active vessels [10,22]. In the present study, contrast solubility contributed to dispersion as well as the administration of a large volume that was ten-fold higher than the dose indicated for use in living animals (2 mL/kg), even without active vascularization or gastrointestinal motility.…”

“…The choice of an image diagnostic for anatomical studies in preserved organisms must take into account the structures or organs to be explored, the preservation method, the protocols and equipment to be used, the operator's ability, and the techniques and parameters that can contribute to the formation of the images [22,31].…”

“…Parallel with Cabreraa et al (2015), the CT images of the brain and associated structures of normal neonatal foals provided excellent detail of clinical anatomy. Previous studies reported the normal anatomy of the equine head showed similar results with CT images (Arencibia et al, 2000;Smallwood et al, 2002;De Zani et al, 2010).…”
