Dorsal nigral hyperintensity abnormality in 7T MRI is a biomarker for diagnosis of Parkinson’s disease and atypical parkinsonisms

Motivation: The dorsal nigral hyperintensity (DNH) abnormality is a characteristic feature of PD and 7T MRI has proved useful for its visualization. Goal(s): To investigate the diagnostic efficiency of DNH abnormality at different stages of PD and in atypical parkinsonisms using 7T MRI. Approach: PD, RBD, MSA-P, MSA-C, and PSP patients and controls underwent 7T T2* with DNH abnormality assessed for diagnostic performance. R2* mapping and principal component analysis were performed in substantia nigra. Results: MSA-C and RBD demonstrated higher preservation rate of DNH than PD, MSA-P, and PSP. DNH scoring criteria proved an optimal diagnostic method of PD, RBD, MSA-P, MSA-C, and PSP. Impact: MSA-C and RBD patients had higher dorsal nigral hyperintensity (DNH) preservation rate compared with PD, MSA-P, and PSP. The DNH scoring criteria proved an optimal diagnostic method of PD, RBD, MSA-P, MSA-C, and PSP.

Abstract

Motivation: The dorsal nigral hyperintensity (DNH) abnormality is a characteristic feature of PD and 7T MRI has proved useful for its visualization. Goal(s): To investigate the diagnostic efficiency of DNH abnormality at different stages of PD and in atypical parkinsonisms using 7T MRI. Approach: PD, RBD, MSA-P, MSA-C, and PSP patients and controls underwent 7T T2* with DNH abnormality assessed for diagnostic performance. R2* mapping and principal component analysis were performed in substantia nigra. Results: MSA-C and RBD demonstrated higher preservation rate of DNH than PD, MSA-P, and PSP. DNH scoring criteria proved an optimal diagnostic method of PD, RBD, MSA-P, MSA-C, and PSP. Impact: MSA-C and RBD patients had higher dorsal nigral hyperintensity (DNH) preservation rate compared with PD, MSA-P, and PSP. The DNH scoring criteria proved an optimal diagnostic method of PD, RBD, MSA-P, MSA-C, and PSP.
