Gamuts

The Radiology Gamuts Ontology, a published ontology of radiologic differential diagnosis lists, at gamuts.net.¹ In OIDM it plays two roles at once: it is an index code system listed alongside SNOMED and RadLex as one of the common ontologies,² and it is a registered contributing organization whose organization code is GMTS.³

Gamuts is the single largest source of finding model content. Of the 2,382 definitions published in the corpus, 1,933 carry an OIFM_GMTS_ identifier, credited to the Radiology Gamuts Ontology as the contributing organization. They were produced by a script that scrapes gamut pages, structures the terms with a language model, and emits them for conversion into definitions.

Synonyms and near-synonyms

• Radiology Gamuts Ontology is the full name; gamut alone means one differential list.
• GMTS is the organization code and the middle segment of the identifiers.
• GAMUTS is the system string when a gamut concept is cited as an index code.
• Finding taxonomy is the newer content spine that is expected to supersede much of this material.

Identifier form

Finding models derived from this source carry OIFM_GMTS_######, for example OIFM_GMTS_016552 for urinary tract calculus.

Conflicts

A gamut is a differential diagnosis list, so Gamuts-derived definitions carry diagnoses where OIDM’s authoring guidance would sometimes want an observation. The open definition cleanup plan lists “gamuts reclassification” as a step that “needs design discussion,” and it is the one step in that plan with no agreed approach.⁴ The content roadmap expects the MGB exam-oriented sub-taxonomies to replace many of these definitions.
