Abstract
in English, Russian

The review addresses the combined use of tractography and neuronavigation. Fundamentals of diffusion tensor imaging are given, technical aspects of fiber tracking in general and in depicting separate subcortical tracts are described. Main advantages of the method and possible causes of errors are highlighted. Precision assessment of this technology is given by comparing with results of subcortical neurostimulation. Surgical tactics is described depending on distance between the tumor and subcortical pathways.

Обзор посвящен совместному применению трактографии и нейронавигации. Приведены основы диффузионно-тензорной МРТ, описаны технические аспекты построения трактографии в целом и отдельных проводящих путей. Выделены главные преимущества метода и возможные причины его ошибок. Дана оценка точности этой технологии путем сравнения с результатами подкорковой нейростимуляции. Описана хирургическая тактика при различном расстоянии между опухолью и проводящими путями.

Keywords: DTI; advantages; comparison with subcortical neurostimulation; diffusion tensor imaging; drawbacks; tractography.
