    Magnetic susceptibility components reveal different aspects of neurodegeneration in alpha-synucleinopathies by Oliver C. Kiersnowski, Pietro Mattioli, Lucia Argenti, Laura Avanzino, Francesco Calizzano, Andrea Diociasi, Laura Falcitano, Chunlei Liu, Mattia Losa, Federico Massa, Silvia Morbelli, Beatrice Orso, Elisa Pelosin, Stefano Raffa, Matteo Pardini, Dario Arnaldi, Luca Roccatagliata, Mauro Costagli

    Published 2025-02-01
    “…Abstract Nigrostriatal dopaminergic degeneration in alpha-synucleinopathies is indirectly reflected by low dopamine transporter (DaT) uptake through [123I]FP-CIT-SPECT. Bulk magnetic susceptibility ( $$\chi$$ ) in the substantia nigra, from MRI-based quantitative susceptibility mapping (QSM), is a potential biomarker of nigrostriatal degeneration, however, QSM cannot disentangle paramagnetic (e.g. iron) and diamagnetic (e.g. myelin) sources. …”
