Context Group Extension Flag Attribute

Tag(0008,010B)
TypeOptional (3)
KeywordContextGroupExtensionFlag
Value Multiplicity1
Value RepresentationCode String (CS)

Indicates whether the triplet of Code Value (0008,0100) (or Long Code Value (0008,0119) or URN Code Value (0008,0120))/Coding Scheme Designator (0008,0102)/Code Meaning (0008,0104) is selected from a private extension of the Context Group identified in Context Identifier (0008,010F). See Section 8.7.

Enumerated Values:

Y

N

Note

Part of the Frame Anatomy Functional Group Macro with usage: C

Required if Body Part Examined (0018,0015) is present and contains a value defined in Annex L “Correspondence of Anatomic Region Codes and Body Part Examined Defined Terms” in PS3.16, or Anatomic Region Sequence (0008,2218) was present in any of the Classic Images that were converted.

Section 8.7

8.7 Context Group Extensions

Context Group Extension Flag (0008,010B) may be used to designate a pair of Code Value (0008,0100) (or Long Code Value (0008,0119) or URN Code Value (0008,0120)) and Code Meaning (0008,0104) as a selection from a private extension of a Context Group. If the Context Group Extension Flag (0008,010B) is present, and has a value of "Y", Context Group Extension Creator UID (0008,010D) shall be used to identify the person or organization who created the extension to the Context Group. Context Group Local Version (0008,0107) conveys an implementation-specific private version DateTime of a Context Group that contains private extensions.

Note

  1. These Attributes provide the means for implementations to extend code sets conveniently, while preserving referential integrity with respect to the original Context Group Version (0008,0106).

  2. The locally-defined (private) value of Context Group Local Version (0008,0107) typically would be a more recent date than the standard value of Context Group Version (0008,0106) specified in the standard message/terminology Mapping Resource that defines the Context Group.
