Diffusion-weighted MRI and MRS

Research summary

Our technical work on diffusion-weighted MRI and MRS focuses on the following directions:

  • Development of diffusion acquisition techniques to overcome the limitations of single-shot EPI.
  • Development of diffusion signal modeling techniques.
  • Removal of the confounding effect of fat in diffusion measurements of the water component in tissues (e.g. skeletal muscle, bone marrow).
  • Development of high b-value DW-MRS to measure diffusion properties of fat and adipose tissue.
