## [Regarding the NIR centralised registry. Is that going to contain any radiology/imaging documentation or is that more of an index to help know which community members have data for which patients?](https://developer.community.nhs.uk/t/regarding-the-nir-centralised-registry-is-that-going-to-contain-any-radiology-imaging-documentation-or-is-that-more-of-an-index-to-help-know-which-community-members-have-data-for-which-patients/14658)
