Susceptibility and diffusion MRI biomarkers predict development of Parkinsonism in iRBD

npj Parkinson's Disease
Quantitative MRI techniques, including quantitative susceptibility mapping (QSM) and diffusion tensor imaging (DTI), may detect early neurodegenerative changes in ɑ-synucleinopathies, especially within the midbrain.

Iron-induced relaxation mechanisms in the human substantia nigra: Towards quantifying iron load in dopaminergic neurons

, 2018
Pathological iron accumulation in the human brain is a biomarker for neurodegeneration. Several diagnostically promising MR- based methods for in vivo iron quantification were proposed, based on the empirical relationship between R 2 * and iron ...
