Formal name of the code system

Digital Imaging and Communications in Medicine

Short name or abbreviation of the code system name

Technical identifier/s of the code system (OIDs, URNs etc)

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.

  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
