This digital poster session highlights innovative applications of quantitative neuroimaging and computational methods across a broad spectrum of neurological, psychiatric, and systemic conditions. Presentations feature advanced MRI and PET techniques (e.g., QSM, ultra-high-field imaging, morphometry, metabolic imaging), studies of iron, tau, amyloid, and cortical organization, and emerging AI approaches for anomaly detection and prognosis prediction. Together, the digital posters demonstrate how cutting-edge imaging biomarkers and data-driven tools are expanding our understanding of brain structure, function, and vulnerability across health and disease.
