Parkinsonism diagnosis: MRI versus PET techniques


  • MRI susceptibility map-weighted imaging (MRI SMWI) and N-3-fluoropropyl-2-β-carbomethoxy-3-β-(4-iodophenyl) nortropane PET (18F-FP-CIT-PET) have similar diagnostic performance for parkinsonism disorders, each with 100% sensitivity.

Why this matters

  • Similar diagnostic performance of SMWI and 18F-FP-CIT-PET indicates that both are viable options for clinical prediction of presynaptic dopaminergic function.
