Principios de Tractografía Cerebral

Principles of brain tractography

Objetivo: hacer una revisión de los principales tractos cerebrales y sus aplicaciones en las neurociencias a partir de la experiencia en la Fundación Universitaria de Ciencias de la Salud (FUCS), Bogotá D.C., Colombia. Materiales y métodos: revisión bibliográfica y utilización de imágenes con resonadores de 1.5 T o 3 T para describir las imágenes de tractografía en enfermedades del sistema nervioso central. Resultados: se muestran las características principales de la tractografía basados en casos de nuestra institución. Discusión: en la gran mayoría de patologías cerebrales no hay estudios sobre la utilidad de la tractografía. Aunque es un estudio disponible en la actualidad, es poca la información que suele obtenerse a nivel clínico, pues toma bastante tiempo el posproceso  de las imágenes y en la mayoría de centros no está protocolizada la secuencia de obtención de la reconstrucción de cada uno de los tractos por separado. Conclusiones: es posible reconstruir los principales tractos cerebrales con escáneres de 1.5 T y 3 T, identificando las vías clave del cerebro y su relación con tumores cerebrales, trauma craneoencefálico, abuso de sustancias y otras afecciones.
