Query: aDWI-BIDS: an extension to the brain imaging data structure for advanced
  diffusion weighted imaging   Diffusion weighted imaging techniques permit us to infer microstructural
detail in biological tissue in vivo and noninvasively. Modern sequences are
based on advanced diffusion encoding schemes, allowing probing of more
revealing measures of tissue microstructure than the standard apparent
diffusion coefficient or fractional anisotropy. Though these methods may result
in faster or more revealing acquisitions, they generally demand prior knowledge
of sequence-specific parameters for which there is no accepted sharing
standard. Here, we present a metadata labelling scheme suitable for the needs
of developers and users within the diffusion neuroimaging community alike: a
lightweight, unambiguous parametric map relaying acqusition parameters. This
extensible scheme supports a wide spectrum of diffusion encoding methods, from
single diffusion encoding to highly complex sequences involving arbitrary
gradient waveforms. Built under the brain imaging data structure (BIDS), it
allows storage of advanced diffusion MRI data comprehensively alongside any
other neuroimaging information, facilitating processing pipelines and
multimodal analyses. We illustrate the usefulness of this BIDS-extension with a
range of example data, and discuss the extension's impact on pre- and
post-processing software.
