NIfTI-MRS Example Data: Magnetic Resonance Spectroscopy Files

Example data files for the NIfTI-MRS format specification for magnetic resonance spectroscopy (MRS) and spectroscopic imaging (MRSI). The dataset was created by William T. Clarke from the University of Oxford and includes manually and programmatically converted data from various MRS sequences. Files include examples of SVS, MEGA-PRESS, CSI, and sLASER-localised data.

Use Cases

• Testing MRS data format compatibility based on the described NIfTI-MRS specification
• Developing software for MRS data processing based on example files for SVS, CSI, and MRSI sequences
• Validating spectroscopic imaging analysis pipelines using the provided variable echo time and fingerprinting examples
• Benchmarking MRS data conversion tools against the manually and spec2nii-converted file examples

Strengths

• Dataset is directly linked to a formal data format specification (NIfTI-MRS)
• Includes examples from multiple common MRS sequences such as STEAM, MEGA-PRESS, and CSI
• Provides both manually converted and tool-generated (spec2nii) files for comparison

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
