2021 Frontiers in Neuroscience  
BackgroundEmerging evidence indicates that iron distribution is heterogeneous within the substantia nigra (SN) and it may reflect patient-specific trait of Parkinson's Disease (PD).  ...  The bilateral SN were segmented based on preoperative quantitative susceptibility mapping to extract susceptibility features using RA-ML.  ...  The texture analyses of the SN showed the superiority of QSM to R2 * map in discriminating PD and HC in one study .  ...

Methodological Considerations for Neuroimaging in Deep Brain Stimulation of the Subthalamic Nucleus in Parkinson's Disease Patients

Bethany R. Isaacs, Max C. Keuken, Anneke Alkemade, Yasin Temel, Pierre-Louis Bazin, Birte U. Forstmann
2020 Journal of Clinical Medicine  
Deep brain stimulation (DBS) of the subthalamic nucleus is a neurosurgical intervention for Parkinson's disease patients who no longer appropriately respond to drug treatments.  ...  One solution for increasing the success and efficacy of DBS is to optimize preoperative planning procedures via sophisticated neuroimaging techniques such as high-resolution MRI and higher field strengths  ...  The top row shows MP2RAGE T1-weighted, T1, T2*, and R2* maps and a quantitative susceptibility map (QSM) image obtained at 7 T within a single multi echo (ME) MP2RAGE sequence.  ...
