Both 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.
