## Resource Profile: AU Base Diagnostic Imaging Result

Official URL: http://hl7.org.au/fhir/StructureDefinition/au-imagingresult | Version: 5.1.0-preview
Standards status: Trial-use | Maturity Level: 1 | Computable Name: AUBaseDiagnosticImagingResult

This profile defines an observation structure to represent a imaging examination result issued by a diagnostic service provider in an Australian context. The observation may represent the conclusions of a diagnostic procedure such as Left retina Foveal thickness by OCT, or it may group the set of results produced by a multi-test study or panel such as Biophysical profile panel.

### Usage Notes

Profile specific implementation guidance:

- The BodyStructure Reference extension may be suitable for use where
  - body site is not implicit in the code found in `Observation.code` and
  - body site information cannot be adequately captured by a single inline coded element in `Observation.bodySite`.
- When sending an observation that represents a study series or panel:
  - the group / panel code is sent in `Observation.code`
  - the overall comments are sent in `Observation.note`
  - the global interpretation by the producer of the study is sent in `Observation.interpretation`
  - individual results may be sent in `Observation.component` or by referencing individual observation results in `Observation.hasMember`
- When sending observations that group the set of results of a multi-modality procedure:
  - A multi-modality procedure observation is sent with individual component examinations in `Observation.hasMember`.
  - An individual component examination observation is referenced by that multi-modality procedure observation (`Observation.hasMember`) rather than directly at the diagnostic report level (`DiagnosticReport.result`).

Usage:

- Refer to this Resource Profile: AU Base Diagnostic Report, AU Base Diagnostic Result, AU Base Diagnostic Imaging Report and AU Base Diagnostic Imaging Result
