We concur with the recommendation of LOINC as the vocabulary standard for this domain. The Regenstrief Institute and the RSNA have created a unified terminology standard for radiology procedures that builds on the strengths of LOINC and the RadLex Playbook. The LOINC/RSNA Radiology Playbook File now contains a unified representation of all existing LOINC and RadLex Playbook content, connecting LOINC radiology terms to a rich set of attributes represented with Radlex terms. The LOINC/RSNA Radiology Playbook File is now jointly published as part of the main LOINC release and it's Maturity should be listed as Production (it is actively being used by radiology centers, in health information exchanges, etc).

In addition, Regenstrief curates a value set of LOINC Imaging Document Codes (OID: that contains terms for imaging procedures/reports from Radiology, Endoscopy, Cardiology, and other imaging specialties. This is the value set named in C-CDA’s Diagnostic Imaging Report template and DICOM’s standard for Imaging Reports using HL7 CDA.
