This page is part of the MII Implementation Guide Bildgebung (v2027.0.0-ballot.1: Release) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version. For a full list of available versions, see the Directory of published versions
Technical guidance for DIC implementers of the Bildgebung module: the context within the overall project, the relations to other KDS modules, and the underlying standards and references.
Imaging modalities are of essential importance for medical diagnostics and consequently serve as one of the foundations for therapy decisions and treatment planning as well as for research purposes. However, the degree of structuring and the way image data are described vary considerably between sites. A comprehensive overview of the availability of structured image data at the consortium sites is currently not available. This circumstance is accounted for by the proposed staged provision of data, which depends on the data available.
Within the MII, the KDS module Bildgebung was the first comprehensive FHIR-based information model for imaging data developed and published in the German context. Other national initiatives, such as MIO42, were involved in the development and have adopted structural modelling decisions. At the European level, the work within the European Health Data Space (EHDS) is particularly relevant; harmonization proposals for imaging data models are currently being discussed there. The MII KDS module Bildgebung is being reviewed for possible adaptation and compatibility needs in every release. The model of the Swiss Personalized Health Network (SPHN) also contains individual conceptual approaches that could become relevant for the future development of the module.
Imaging studies are assigned to a patient via references from the study resource (ImagingStudy) to the module PERSON. Likewise, the diagnostic report (DiagnosticReport) and the request (ServiceRequest) reference the module PERSON.
Imaging studies are assigned to an encounter via references from the study resource (ImagingStudy) or the diagnostic report (DiagnosticReport) to the module FALL. A reference to the respective encounter should always be carried along to establish the relation of the imaging study to that encounter.
In connection with imaging modalities there can be relations to performed procedures, for example an MRI examination before an operation. For information about the performed procedure, the module PROZEDUR is used in the resources study (ImagingStudy), diagnostic report (DiagnosticReport) and in the linked resource generic observation (Observation).
The previous finding resource (Condition) contains links to the module DIAGNOSE, which make it possible to record the imaging examination as a diagnostic tool supporting the diagnosis. These are represented via a reference in the request resource (ServiceRequest), which in turn is referenced in the diagnostic report (DiagnosticReport).
To represent contrast administration, both the imaging procedure (Procedure) and the study (ImagingStudy) establish a relation to the module MEDIKATION. In the imaging procedure, the contrast administration is represented via the medication administration (MedicationAdministration), and in the study (ImagingStudy) it is additionally complemented by the medication statement (MedicationStatement).
The Core Dataset module Bildgebung follows the common technical standards of medical imaging. This primarily concerns the DICOM standard for FHIR profiling of relevant technical and medical concerns.
The code systems, terminologies and references used for procedures, diagnoses and related medical concerns are:
Reporting-specific extension modules and reporting profiles that reference this implementation should follow the common reporting guidelines and criteria, e.g.:
In addition, the HL7 FHIR core specification was used — in particular the resources ImagingStudy and DiagnosticReport, and additionally the resources Observation, Composition, BodyStructure and ServiceRequest.
This specification was designed on the basis of the description of the MII Core Dataset in the version of 10 March 2017 (PDF) and the dataset description in ART-DECOR.
