Diagnostic Utility of Dorsolateral Nigral Hyperintensity with Susceptibility Map‐Weighted Imaging in Degenerative Parkinsonism Compared to Other Movement Disorders

SMWI is an accurate and reproducible imaging technique for diagnosing neurodegenerative parkinsonism, comparable to previously reported DAT-scan accuracy. Other sequences used to assess the DNH such as regular Susceptibility Weighted Imaging have shown variable results, particularly when studying disease controls. These findings support the adoption of SMWI as a standard commercial sequence in clinical MRI platforms.
