NiBabel

NiBabel is an active Python package that provides read and write access to a wide array of neuroimaging file formats, including NIfTI, ANALYZE, GIFTI, MINC, MGH, ECAT, Philips PAR/REC, AFNI BRIK/HEAD, and CIFTI-2, with limited support for DICOM. It enables users to interact with image data as NumPy arrays and access format-specific metadata through structured headers. Currently at version 5.4.2, NiBabel maintains a consistent release cadence with frequent bug-fix and feature updates.
