Diffusion Tensor Imaging of the Basal Ganglia for Functional Neurosurgery Applications.

Diffusion Tensor Imaging of the Basal Ganglia for Functional Neurosurgery Applications. Prog Neurol Surg. 2018;33:62-79 Authors: Sammartino F, Hodaie M Abstract Since its introduction, diffusion tensor imaging (DTI) has become an important tool in neuroscience given its unprecedented ability to image brain white matter in vivo. The interest in understanding the mechanisms of action of Deep Brain Stimulation in different targets and indications, together with the constant drive towards the improvement in long-term clinical outcomes, has found a logical complement in the application of tractography in this field. Diffusion tensor imaging has been traditionally associated with an increased susceptibility to MRI artifacts, and expensive computational resources. Recent advances have however improved these restrictions, allowing for countless applications in Neurosurgery, as demonstrated by the large number of original research papers published in the last decade. In this chapter, we review the current status of the implementation of DTI during DBS of the basal ganglia, discussing the findings, potential challenges and the expected improvements in surgical outcomes deriving by the routine use of tractography in functional neurosurgery.
