LOINC/RSNA Radiology Playbook
The radiology portion of LOINC, developed jointly by the Regenstrief Institute and the RSNA, which names imaging orderables along axes such as modality, anatomy, and technique.1 It is “actively governed, and freely licensed for commercial and non-commercial use. The Playbook ships twice yearly under joint Regenstrief/RSNA governance, but it is a separate artifact” from RadLex.2
In OIDM the Playbook is the stated basis for exam types, and it appears only in design documents. The terminology tool’s roadmap makes it “first-class in radiology,” planning to detect both LOINC codes and legacy RPID Playbook identifiers, to rank orderable queries toward Playbook terms while ranking finding and anatomy queries toward RadLex, and to carry Playbook, RPID, and RadLex anatomy correspondences in crosswalk provenance.3 The earliest statement of the idea is older still: the curated anatomic location set’s roadmap calls for “a companion for exam types based on LOINC/RadLex Playbook exam definitions that specify all included body parts for the exam.”4
Synonyms and near-synonyms
- Playbook and RSNA Playbook are the short forms.
- RadLex Playbook is the historical name; its
RPIDidentifiers persist as legacy codes. - LOINC is the containing system; the Playbook is the radiology subset with its own governance.
- Exam type is the OIDM concept the Playbook is meant to supply identifiers for.
Identifier form
LOINC codes for current content; RPID followed by digits for legacy Playbook identifiers.

Conflicts
Nothing in OIDM consumes the Playbook today. Playbook support is planned in the terminology tool but unimplemented, no modality or body-part axis parsing exists, and RadLex merely cites “Playbook” as free-text provenance on individual concepts rather than linking to it.2
