Scope/domain statement for the code system

(Official or from HTA)

DICOM® (Digital Imaging and Communications in Medicine) is the international standard to transmit, store, retrieve, print, process, and display medical imaging information.

DICOM primarily adopts existing codes from SNOMED, LOINC, UCUM, IEEE, etc. into DICOM code sets referred to as Context Groups (CIDs).  DICOM also defines new codes for concepts that do not clearly fall into those other coding schemes.

Coded concepts defined in "PS 3.16" Digital Imaging and COmmunications in Medicine (DICOM) - Part 16: Content Mapping Resource, Annex D: DICOM Controlled Terminology Definition

Process to request content change

Small changes, such as adding or correcting codes, are called Change Proposals (CPs) which are processed by DICOM Working Group 6 (WG-6).  https://www.dicomstandard.org/submitcp
Large extensions to the standard are called Supplements and follow a Workitem approval and development process.  https://www.dicomstandard.org/submitworkitem

  1. DICOM is not a terminology. DICOM uses IEEE 11073 (Rosetta) and Radlex.

    1. it is true that some of DICOM does use IEEE 11073, but DICOM is an author of vocabulary.

      Please contact the co-chairs of the joint HL7/DICOM workgroup known in HL7 as "Imaging Integration" Christopher Lindopand Jonathan Whitby

  2. Thanks John. I added some text and tidy up above to reflect that.  Hope that's appropriate.

  3. Thanks, Kevin O'Donnell One of our challenges, and indeed one of the main reasons we publish these pages, is to try to find who can authoritatively provide the information that the community needs about these code systems.  DICOM and more particularly IEEE is something I've asked Melvin Reynolds and previous co-chairs of the II WG about in the past, so having up-to-date information and contacts for the community is great, thank you.

    1. for IEEE 11073 I would recommend Paul Schluter as he is the owner of the Rosetta

  4. Julie James - the URL documented here (https://www.dicomstandard.org/) in 2019, may not have been intended to be used as a URI for the DICOM coded concepts. We did have a more specific URL (http://dicom.nema.org/medical/dicom/current/output/chtml/part16/PS3.16.html) in the additional information section. The URI "http://dicom.nema.org/resources/ontology/DCM" has been used by HL7 implementers and redirects to the latter link above. I'd suggest we update this HTA page to be consistent (i.e., change the URI to "http://dicom.nema.org/resources/ontology/DCM") and work with UTG to ensure all of it's resources reflect the same. Ted Klein

  5. Jessica Bota please start the process in UTG Jira to make the DICOM change

  6. Hi all. The DICOM changes have been created and submitted. See  UP-96 - Getting issue details... STATUS

    This ticket is in Consensus Review, so please review and vote to push the changes through. Please see Vocabulary Maintenance at HL7 for more info on becoming a Reviewer and links to documentation for the voting process. Please reach out if you have any questions. 

  7. Hi all, friendly reminder to vote on this proposal (see comment above). Caroline Macumber Julie James Reuben Daniels
