Susceptibility Weighted Imaging (SWI) and T2 star (T2*) imaging can measure the
brain iron deposition. However, the two ways by which the brain iron is
measured are not compared. This study measured the brain iron of healthy
volunteers and Parkinson’s disease patients by SWI and T2* imaging. we found
that SWI and T2* imaging could estimate the brain iron, and the SWI radiant
values of SNr and RN were significance difference between healthy volunteers
and Parkinson’s disease patients, suggesting the SWI had better reliability to
diagnose the Parkinson’s disease than the T2* imaging.
