This systematic review evaluated the diagnostic performance of combining neuromelanin-sensitive MRI (NM-MRI) and quantitative susceptibility mapping (QSM) in Parkinson's disease (PD) across 17 studies involving 2228 participants. The integration of these imaging techniques significantly improved diagnostic accuracy, with AUC values ranging from 0.86 to 0.99, effectively differentiating PD from healthy controls.

Key findings

  • Combined NM-MRI and QSM showed reduced neuromelanin volume and increased iron deposition in PD patients.
  • The multimodal approach yielded AUC values between 0.86 and 0.99 for diagnostic accuracy.
  • Recent advances included AI-driven automated segmentation, reducing scan times and enhancing reproducibility.

Why it matters

The findings highlight the potential of advanced imaging techniques to enhance the accuracy of Parkinson's disease diagnosis, which is crucial for timely intervention and management of the condition.
