Sponsor

Min Zhao,MD

Enrollment

90 participants

Start Date

Sep 14, 2024

Study Type

OBSERVATIONAL

Conditions

Multiple System Atrophy - Parkinsonian Subtype (MSA-P)Multiple System Atrophy - Cerebellar Subtype (MSA-C)

Summary

The aim of this study was to apply PET/MR techniques targeting TSPO to explore the temporal and spatial alterations characterizing neuroinflammation in MSA patients, and to assess its value as a biomarker for diagnostic typing, disease severity, and prognosis of MSA disease.
