Executive Industry Relevance

Automated segmentation of human brown adipose tissue (BAT) using co-registered PET-CT and MRI enables quantitative, non-invasive assessment of BAT depots, addressing a key challenge in metabolic disease research. This workflow enhances predictive confidence in tissue identification and supports translational continuity from discovery to preclinical model development. The approach positions MRI-based BAT quantification as a scalable, radiation-free alternative for future metabolic and obesity-targeted R&D portfolios.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables objective identification and localization of BAT depots for mechanistic studies.
• Supports biological de-risking by distinguishing BAT from other adipose tissues using quantitative imaging metrics.
• Facilitates functional target validation for metabolic pathway interrogation.

Screening & Assay Development

• Provides standardized, automated BAT masks for reproducible imaging-based assays.
• Delivers quantitative MRI outputs suitable for high-confidence screening of metabolic modulators.
• Enables assay scalability and platform reuse by eliminating manual segmentation variability.

Translational & Preclinical Research

• Aligns imaging biomarkers with disease-relevant metabolic endpoints for translational studies.
• Supports continuity from human imaging to preclinical model validation of BAT-targeted interventions.
• Reduces biological ambiguity in preclinical efficacy assessments by leveraging quantitative imaging data.

Pipeline & Workflow Integration

This automated imaging protocol integrates into the discovery-to-preclinical continuum, bridging early mechanistic studies and translational research in metabolic disease.

• Discovery Biology: Enables hypothesis testing and pathway clarification through precise BAT localization and quantification.
