Why neuroimaging leads in qMRI
Biomarkers for early detection
Iron accumulation, demyelination and microhemorrhage alter tissue properties before atrophy appears.
Longitudinal tracking
Chronic disease is tracked over years, so reproducible absolute values matter more than any single image.
Small structures made visible
Sharper gray/white matter and subcortical contrast resolves millimetric targets such as the GPi and internal lamina in DBS planning.
CLINICAL UTILITY
DBS planning
Subcortical targeting and iron-sensitive biomarkers.
TBI
Trauma lesions and vascular injury, relevant to TBI reporting.
Neuro-Onc
Necrosis from treatment effect and tissue properties.
Microbleeds
Detection of microbleeds linked to anti-amyloid therapy (ARIA).
Parkinson's, MS, etc.
Biomarker and tissue property changes tracked over time.
