Introducción: El sistema ventricular encefálico es muy complejo, y es especialmente difícil de comprender para los estudiantes de pregrado. Clásicamente, la anatomía ventricular puede enseñarse usando encéfalos cadavéricos, imágenes de tomografía o resonancia magnética. Presentamos nuestra experiencia con el uso de imágenes tridimensionales obtenidas mediante un sistema de neuronavegación. Material y métodos: Se obtuvieron imágenes de resonancia magnética de 3 pacientes. Las imágenes fueron introducidas en un sistema de neuronavegación y se reconstruyó específicamente el sistema ventricular encefálico y algunas estructuras gangliobasales. Posteriormente se solicitó la opinión de 38 estudiantes de pregrado que cursaban la materia neuroanatomía, sobre la utilidad de las imágenes en el estudio del sistema ventricular.Discusión: todas las imágenes obtenidas fueron de buena calidad, el 100% de los estudiantes manifestó que las imágenes eran muy útiles o esenciales para comprender cabalmente la anatomía ventricular. Conclusiones: el uso de imágenes obtenidas por un sistema de neuronavegación son útiles en la enseñanza de la anatomía del sistema ventricular encefálico.
AIntroduction: Anatomy of cerebral ventricles is very complex. Classically, ventricular system anatomy has been taught employing cadaveric brains and CT or MRI images. We present 3D images of the ventricular system obtained by neuronavigation system and the results of its use in teaching anatomy of cerebral ventricles. Material and methods: Magnetic resonance images of three patients were obtained. These images were transferred to a neuronavigation system, and a 3D reconstruction of cerebral ventricles, were performed. Afterwards, 38 undergraduate students were required to give their opinion about how useful the images are in order to study the cerebral ventricles. Results: One hundred percent of the students agreed that the images were very useful or even essential to utterly comprehend the ventricular anatomy. Discussion: As other authors, we think that 3D images are very useful as a complement for teaching anatomy of cerebral ventricles. Conclusions: Employment of 3D images obtained in a computer system are useful for teaching the encephalic ventricular system anatomy, as a complementary tool.
