Area of Science:

  • Neuroimaging
  • Biomedical Engineering
  • Medical Physics

Background:

  • Magnetic resonance spectroscopy (MRS) enables non-invasive in vivo neurochemical and metabolic measurements.
  • Traditional MRS applications, like single-voxel spectroscopy for neonatal ischemia detection, had limited clinical utility due to simplified data analysis.
  • Advancements in scanner power and MRS sequences have increased data complexity, necessitating sophisticated image processing techniques.

Conclusions:

  • The developed framework facilitates robust access and manipulation of complex MRS data.
  • Characterizing MRS image processing considerations lowers the barrier to entry for neuroimaging researchers.
  • This work supports advanced research and innovation in the field of MRS.
