Deep gray matter nuclei (DGMN)
in the human brain play an important role for numerous diseases like Alzheimer’s
disease. Thus, the characterization of DGMN in the framework of multiple
MR-based physiologic parameters (like magnetic susceptibility or electric
conductivity) is expected to be helpful for understanding these diseases. This
study investigates – to the best of our knowledge, for the first time - the
electric conductivity of DGMN in healthy volunteers, reflecting the electrolyte
content of these nuclei. Conductivity determination is boosted by utilizing
geometry information obtained from susceptibility maps during conductivity
reconstruction.
