HL7 Europe Imaging Study Report
0.1.0 - ci-build 150

HL7 Europe Imaging Study Report, published by HL7 Europe. This guide is not an authorized publication; it is the continuous build for version 0.1.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7-eu/imaging/ and changes regularly. See the Directory of published versions

Open Topics

This page contains open topics detected in the specification that are recognized and still need to be resolved.

  • The definition of what a information recipient is is not completely clear. We follow the guidance from hdr in this until more information is available. If it represents a request for info - CommunicationRequest would be an option, if it represents a log of who received the info, Communication or Provenance could address this.
    • Guidance from HL7-EU meeting -> is the party that originally requested the document.
  • Include A.4 Specimen as it sounds like requiring a Digital Pathology report which may have a different structure from a radiology report.
    • The Specimen does not refer to digital pathology but to a sample taken from the body and scanned using normal imaging devices. Refine model accordingly.
  • Add invariant stating that Composition.identifier SHALL be equal to one of the DiagnosticReport.identifier, if at least one exists.

  • DiagnosticReport.code and Composition.type are bound to a value set with one LOINC code. The value set should be replaced. The best candidate it the (FHIR version) of Radlex/LOINC playbook, as proposed by IDR.

  • DiagnosticReport.code and Composition.type should match enforced by an invariant.

  • Likewise, DiagnosticReport.status and Composition.status shall be aligned, thus an invariant should be implemented.

  • Content in Composition and DiagnosticReport
    • Is all eHN information required to be in both?
    • HL7-WGN feedback:
      • DiagnosticReport is the intended to be used to search for documents (not relying on the Composition), the Composition is a representation of the contents. Hence all/most search options should be present on DiagnosticReport.
  • Provide description of contents of section.title and text; add documentation on the generation of the document and the role of resource.text and Composition.section.text.
    • HL7 WGM preliminary conclusion: Narrative is generated from the structured content.
    • TBD where to add free-text notes - note extension? (annotation)

  • Provide narrative on the use of the model and define the mandatory relationships between resources (e.g. DR.conclusion and Comp.section.text)

  • Some ValueSets refer to EDQM codes - where is this code system defined?
    • HL7-EU terminology server
    • TBD add reference

  • Check whether we need to refer to https://dicom.nema.org/medical/dicom/current/output/chtml/part06/chapter_A.html for document categories or types.

  • Check whether Diagnostic Imaging Report titles could benefit from https://dicom.nema.org/dicom/2013/output/chtml/part16/sect_CID_7000.html

  • Add section explaining where this specification deviates/aligns with IDR.
    • TBD - planned after publication of initial IHE-IDR IG mapping.
  • Refine use of accession number and order id (https://confluence.hl7.org/spaces/HEU/pages/321160132/2024-02+HL7+EU+WGM+-+EU-a-thon+-+imaging+discussions#id-202402HL7EUWGMEUathonimagingdiscussions-SearchbyorderId)
    • Order ID is id of original order
    • Accession Number is id assigned by the RIS.
