Tractography, a non-invasive method using MRI, virtually reconstructs central nervous system axon bundles. Understanding its applications and limitations is crucial as it moves toward routine clinical use.

Area of Science:

  • Neuroimaging
  • Neuroanatomy
  • Medical Technology

Background:

  • Diffusion-weighted magnetic resonance imaging (DW-MRI) is a key technology.
  • Tractography offers a non-invasive approach to visualize neural pathways.
  • Accurate in vivo study of the central nervous system's white matter architecture is challenging.

Purpose of the Study:

  • To describe the current state of tractography.
  • To highlight its potential for clinical applications.
  • To discuss the importance of understanding tractography's capabilities and constraints.

Main Methods:

  • Utilizes diffusion-weighted magnetic resonance images.
  • Employs computational algorithms for virtual reconstruction of axon bundles.
  • Focuses on non-invasive in vivo imaging techniques.
