Neuromelanin-MRI to Quantify and Track Nigral Depigmentation in Parkinson's Disease: A Multicenter Longitudinal Study Using Template-Based Standardized Analysis (2022)
Journal Article
Xing, Y., Sapuan, A. H., Martín-Bastida, A., Naidu, S., Tench, C., Evans, J., …Auer, D. P. (2022). Neuromelanin-MRI to Quantify and Track Nigral Depigmentation in Parkinson's Disease: A Multicenter Longitudinal Study Using Template-Based Standardized Analysis. Movement Disorders, 37(5), 1028-1039. https://doi.org/10.1002/mds.28934

Background: Clinical diagnosis and monitoring of Parkinson's disease (PD) remain challenging because of the lack of an established biomarker. Neuromelanin-magnetic resonance imaging (NM-MRI) is an emerging biomarker of nigral depigmentation indexing...

Relationship between neuromelanin and dopamine terminals within the Parkinson’s nigrostriatal system (2019)
Journal Article
Martín-Bastida, A., Lao-Kaim, N. P., Roussakis, A. A., Searle, G. E., Xing, Y., Gunn, R. N., …Piccini, P. (2019). Relationship between neuromelanin and dopamine terminals within the Parkinson’s nigrostriatal system. Brain, 142(7), 2023–2036. https://doi.org/10.1093/brain/awz120

© 2019 The Author(s). All rights reserved. Parkinson's disease is characterized by the progressive loss of pigmented dopaminergic neurons in the substantia nigra and associated striatal deafferentation. Neuromelanin content is thought to reflect the... Read More about Relationship between neuromelanin and dopamine terminals within the Parkinson’s nigrostriatal system.

Coordinate based meta-analysis of motor functional imaging in Parkinson's: disease-specific patterns and modulation by dopamine replacement and deep brain stimulation (2019)
Journal Article
Xing, Y., Tench, C., Wongwandee, M., Schwarz, S., Bajaj, N., & Auer, D. (2020). Coordinate based meta-analysis of motor functional imaging in Parkinson's: disease-specific patterns and modulation by dopamine replacement and deep brain stimulation. Brain Imaging and Behavior, 14(4), 1263–1280. https://doi.org/10.1007/s11682-019-00061-3

Objective To investigate factors affecting the pattern of motor brain activation reported in people with Parkinson’s (PwP), aiming to differentiate disease-specific features from treatment effects. Methods A co-ordinate-based-meta-analysis (CBMA...

Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI (2018)
Journal Article
Xing, Y., Sapuan, A., Dineen, R., & Auer, D. P. (2018). Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI. Movement Disorders, 33(11), 1792-1799. https://doi.org/10.1002/mds.27502

Background: Neuromelanin is a pigment with strong iron-chelating properties preferentially found in dopaminergic neurons of the substantia nigra, pars compacta (SNpc). Parkinson's disease is characterized by pronounced, MRI detectable neuromelanin lo... Read More about Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI.

Parkinson's disease related signal change in the nigrosomes 1–5 and the substantia nigra using T2* weighted 7T MRI (2018)
Journal Article
Schwarz, S. T., Mougin, O., Xing, Y., Blazejewska, A., Bajaj, N., Auer, D. P., & Gowland, P. (2018). Parkinson's disease related signal change in the nigrosomes 1–5 and the substantia nigra using T2* weighted 7T MRI. NeuroImage: Clinical, 19, 683-689. https://doi.org/10.1016/j.nicl.2018.05.027

Improved markers for the progression of Parkinson's disease (PD) are required. Previous work has proven that iron dependent MRI scans can detect the largest Nigrosome (N1) within the substantia nigra (SN) pars compacta and changes in PD. Histopatholo...
