As of the December 2017 LOINC release, we have completed updating all of our radiology content according to the LOINC/RadLex Unified Model, which was developed through our collaboration with the Radiological Society of North America (RSNA).
You can find information about the unified model at the end of this document, in the LOINC/RSNA Radiology Playbook User Guide.
The following table provides a reference for how the attributes in the Unified Model correspond to the primary LOINC Parts.
