Resumen
El artículo describe el método para la elaboración de un atlas digital de la anatomía segmentaria del perro, por crioseccionamiento, mediante las técnicas de tomografía axial computarizada y de resonancia magnética. Dicho atlas es una herramienta didáctica y de apoyo diagnóstico para estudiantes de pre y posgrado, y para los profesionales del área. Para el procedimiento se utilizó una hembra canina, adulta, criolla, de color negro, clínicamente sana, de aproximadamente 4 años de edad, 22 kg de peso y de tamaño mediano (50 cm de altura a la cruz). Los exámenes imagenológicos de tomografía axial computarizada y de resonancia magnética se llevaron a cabo en el Hospital San Vicente de Paúl y en el Instituto de Alta Tecnología Médica de Antioquia (IATM), respectivamente. Se obtuvieron imágenes segmentarias de la estructura corporal total del animal en sus planos frontal, sagital y transverso o axial. Con base en estas imágnes se compararon las estructuras anatómicas con los cortes del cadáver del animal. Además de la utilidad para el atlas digital, las imágenes formarán parte de una base de datos a utilizar en el laboratorio de anatomía animal de la Universidad de Antioquia.
Summary
This article describes the process of creation of a digital atlas of canine anatomy by criosectioning with computed tomography and magnetic resonance. The atlas is intended to be of help for students and practitioners. A medium size, adult, healthy creole, black colored bitch was used, weighing 22 Kg. Computed tomography and magnetic resonance were performed at the San Vicente de Paul Hospital and at the Instituto de Alta Tecnología Médica de Antioquia (IATM), respectively. Segmentary images (frontal, sagital and transverse) of the complete body were obtained and analyzed by comparison with real cuts of the dog's body. Besides its use for the atlas these images are available in the animal anatomy laboratory at the Universidad de Antioquia.
