T2*
weighted MR image is influenced by iron deposition, so that SN shows up
iron-related MRI contrast for all that SN is gray matter. Therefore T2* MR
imaging shows great potential in PD study using ultra high field (UHF) 7.0T.
And 3D T2* Gradient Echo (GE) sequence makes it possible to study a
volumetric analysis and a structural morphometry for SN. This method is
validated, despite the reduced SNR associated with fast imaging techniques.
And 3D model of the SN shows quite well structural changes in PD case.
