This digital poster session focuses on advanced quantitative MRI methods for probing brain microstructure and pathology in neuroinflammation, with particular emphasis on multiple sclerosis and related neurological conditions. Presentations showcase innovations in quantitative susceptibility mapping (QSM), diffusion MRI, myelin-sensitive imaging, ultra-high-field MRI, and AI-based analysis to improve lesion characterization, detect subtle tissue changes, and predict clinical outcomes. Collectively, the posters highlight how cutting-edge acquisition techniques and computational approaches are advancing imaging biomarkers for disease mechanisms, progression, and prognosis.
