Ubiquitous international standard for medical imaging used across equipment manufacturers and modalities. Frequently, researchers will convert DICOM data output by a scanning instrument into NIfTI for analysis and dissemination. DICOM is complex, comprehensive, and highly specific to support needs across the entire spectrum of medical imaging and clinical workflows, while NIfTI is comparatively simple, minimalistic, and easy to support and better suited for research purposes (Li, 2016). NIfTI (Neuroimaging Informatics Technology Initiative), a neuroimagery-specific format designed to support analysis beyond clinical workflow, developed from (and largely compatible with) an older format called ANALYZE.īoth formats offer their own respective pros and cons, and selecting between the two is largely dependent on the needs and niche of the end user. Neuroimaging datasets used by researchers predominantly fall into two main file formats:ĭICOM (Digital Imaging and Communications in Medicine), a ubiquitous and non-proprietary medical imagery format that facilitates communication and exchange across modalities and equipment manufacturers. This guide includes a description of the formats, example datasets which you can view online, recommendations for software for viewing the data, key curatorial considerations, preservation actions, FAIR principles suggestions, ways to use the format and documentation of the curation process. Curating these complex sources of data can be challenging, but this guide can help with curating a specific type of neuroimaging data: fMRI scans that are saved in either NIfTI or DICOM format. The datasets are often large, consisting of many images, and researchers are interested in differing aspects of the data and images, from an entire set of images that create a “virtual brain” to just the metadata of particular types of scans. Images of brains are essential for neuroscience research, but the complexity of the images and their associated data are a challenge to efficiently share and archive. What to look for to make sure file meets Fair Principles These workshops have been generously funded by the Institute of Museum and Library Services # RE-85-18-0040-18.

If not, has the researcher provided documentation of processing procedures?. Has “burned-in” text been removed if PHI?. For high resolution structural images, have facial features been removed from the images?. Has patient data been removed from the header of a DICOM file?. For general neuroimaging data: Brain Imaging Data Structure (BIDS). 
NIfTI: Header consists of standardized series of tags, but few relate to file administration (eg., owner/creator). DICOM: Header consists of standardized series of tags. DICOM: The copyright for the DICOM Standard is held by the National Electrical Manufacturers Association (NEMA) on behalf of the DICOM Standards Committee, administered by the Medical Imaging Technology Association (MITA). NIfTI: The National Institute of Mental Health and the National Institute of Neurological Disorders and Stroke are joint sponsors of the initiative to define and maintain this format. NIFTI-1, NIFTI-2 (not bitwise compatible)ĭiagnostic medical imaging, medical informatics NIfTI: Contains image dataset with an optional JSON file that contains metadata (if converted using dcm2niix). DICOM: A header with demographic information about the patient and metadata about the image(s), followed by image datasets. Neuroimaging DICOM and NIfTI Primer Overview TopicĭICOM.
