Mapeamento quantitativo de suscetibilidade de um cérebro humano usando ressonância magnética ex-vivo

Executive Industry Relevance

Quantitative susceptibility mapping (QSM) using ex-vivo MRI enables precise quantification of brain tissue magnetic properties, directly informing cellular composition such as myelin content. This capability supports mechanistic de-risking and target validation in neurodegeneration and demyelination research. Integrating artifact-suppressed QSM data enhances predictive confidence at key discovery and preclinical inflection points.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables quantitative interrogation of tissue composition relevant to neurological targets.
• Supports biological de-risking by distinguishing myelin and iron content in brain regions.
• Facilitates predictive confidence in target engagement and mechanism-of-action studies.

Screening & Assay Development

• Provides validated imaging readouts for downstream assay development.
• Standardizes artifact removal and signal enhancement for reproducible outputs.
• Enables robust comparison of compound effects on tissue susceptibility in screening workflows.

Translational & Preclinical Research

• Aligns imaging biomarkers with disease-relevant tissue changes in preclinical models.
• Supports continuity from discovery through preclinical validation by quantifying tissue alterations.
• Improves risk-adjusted advancement decisions based on quantitative imaging endpoints.
