Comparing imaging techniques for imaging brain biomarkers in Parkinson’s disease


  • [18F]-flurodeoxyglucose-positron emission tomography (FDG-PET) imaging offers the most consistent results compared with MRI or diffusion tensor imaging (DTI) for examining Parkinson’s disease (PD) markers.

Why this matters

  • PD is the second-most frequently occurring neurodegenerative disease, but diagnosis is still based mostly on clinical symptoms; an unbiased review of imaging techniques for identifying brain biomarkers for PD is needed to aid diagnosis.
