    Transcranial sonography-magnetic resonance fusion imaging shows promise in differentiating Parkinson’s disease from multiple system atrophy-parkinsonian type.

  • 2

    The study included 164 patients with Parkinson’s disease, 71 with MSA-P, and 118 controls, evaluating the diagnostic value of TCS-MR fusion imaging.

  • 3

    Significant differences in SN grades and echogenicity were found among the groups, with TCS-MR fusion imaging outperforming traditional methods.

  • 4

    Maximum echogenicity of SN1 and left SN1 provided the highest diagnostic performance for Parkinson’s disease, with AUC values of 0.86 and 0.82.

  • 5

    TCS-MR fusion imaging may serve as a novel technique for improving the accuracy of Parkinson’s disease diagnosis compared to conventional assessments.
