Area of Science:

  • Neuroimaging
  • Neurology
  • Medical Physics

Background:

  • Many neurological disorders are linked to neocortical gray matter (GM) abnormalities, yet conventional MRI often fails to identify the cause.
  • Imaging the thin, convoluted neocortex is challenging due to the partial volume (PV) effect, limiting diagnostic capabilities.
  • There is a need for advanced MRI techniques to visualize subtle GM changes associated with neurological conditions.

Purpose of the Study:

  • To develop a novel 3D double inversion recovery (DIR) MRI sequence for enhanced neocortical gray matter (GM) imaging.
  • To overcome the limitations of conventional MRI in visualizing the neocortex and its associated pathologies.
  • To improve the efficiency and image quality for high-resolution GM imaging.

Main Methods:
