Foreign Exam Management use cases cover three main areas requiring standardization:

  • Document and Image Sharing
  • Imaging Report Format
  • Anatomic Region Code

Listed below are the available standards considered for each standardization category, the chosen alternative being highlighted.

Document and Image Sharing

Foreign Exam Management will be implemented by an organization participating a jurisdictions’ shared Diagnostic Imaging Repository (DI-R) system.  The DI-R will provide for registration and long term storage of sets of images and reports and standards based services that will be leveraged and, possibly, upgraded to support the FEM use case(s).

Supporting Rationale

IHE Cross-Enterprise Document Sharing - Imaging (XDS/XDS-I)

The IHE XDS-I.b profile specifies the use of existing standards including HL7 and DICOM to enable registration and sharing of images and reports.  A Canadian XDS Affinity domain guide is available to support implementation of the profile.
