PET-BIDS

PET-BIDS standardizes the organization and metadata of positron emission tomography (PET) datasets within the Brain Imaging Data Structure (BIDS) to enable reproducible neuroimaging analyses of brain metabolism, receptor binding, and other molecular processes.

Key Features:

• Standardized format: Specifies BIDS-aligned folder structures and metadata fields tailored for PET datasets to ensure consistent dataset organization.
• PET-specific metadata schema: Defines PET-relevant metadata and requirements that describe acquisition parameters and molecular imaging context.
• File naming and directory conventions: Provides explicit guidelines on file naming conventions and directory structures for PET data organization.
• Validation and conversion support: Supports use of converters and validators that check PET-BIDS compliance and transform datasets into the PET-BIDS structure.
• Facilitates data sharing and aggregation: Enables aggregation and interoperability of PET datasets across studies by enforcing a common standard.

Scientific Applications:

• Brain metabolism quantification: Supports organization of PET data used to quantify cerebral metabolic rates and tracer uptake dynamics.
• Receptor binding studies: Structures datasets for analyses of receptor binding and ligand-specific molecular imaging.
• Molecular imaging method development: Provides standardized inputs for developing and benchmarking analytical methods for PET data.
• Reproducible neuroimaging analyses: Promotes reproducibility in PET-based neuroimaging studies through standardized metadata and file organization.

Methodology:

Defines detailed specifications aligned with BIDS principles, including guidelines for file naming conventions, metadata requirements, and directory structures tailored to PET data, and supports the use of converters, validators, and analysis tools that operate on PET-BIDS datasets.
