Introduction to NIfTI#

The NIfTI (Neuroimaging Informatics Technology Initiative) format is a derivative of the ANALYZE format, which was originally developed for medical imaging.

Why NIfTI?#

Before NIfTI, medical imaging data was stored in a variety of formats, including ANALYZE, MINC, and DICOM.

  • ANALYZE
    • ANALYZE is a proprietary format developed by the Mayo Clinic.
    • ANALYZE files are not widely supported and are often difficult to work with.
  • MINC
    • MINC (Medical Image NetCDF) is a newer format developed by the National Institutes of Health (NIH).
    • MINC files are widely supported and can be easily shared and distributed.
  • DICOM
    • DICOM (Digital Imaging and Communications in Medicine) is a standardized format for medical imaging data.
    • DICOM files are widely supported and can be easily shared and distributed.
