Although a small subset of the larger domain of radiological terms,
imaging signs are of obvious significance to the study of radiology.
More than 350 imaging signs -- with their names, synonyms, definitions,
and related concepts -- provide an important contribution to RadLex.
The integration into the RadLex vocabulary of these terms will have both
academic and clinical implications.
RadLex is a standardized vocabulary of radiological terms. To augment
its terms for anatomy, diagnoses, and radiological observations, we
sought to integrate a set of imaging signs.
We identified a variety of sources of imaging signs, including
Mulligan's Classic Radiologic Signs: An Atlas and History, Gentili's
online "Atlas of Signs in Musculoskeletal Radiology," and articles in
the journals RadioGraphics and Radiology (including the "Signs in
Imaging" series). Within RadLex, the imaging signs were defined as
subclasses of term "imaging sign." For each imaging sign, we included a
canonical name, alternate names, and a concise definition. We also
identified RadLex terms to link the imaging signs to relevant anatomy,
diseases, and imaging modalities. For example, the imaging sign "bamboo
spine" included links to the terms for spine, ankylosing spondylitis,
An initial list of more than 350 imaging signs has been added to the
RadLex vocabulary. Many imaging signs have names derived from reference
to nonmedical concepts (e.g., "bamboo spine", "lemon sign") or eponyms
(e.g., "Rigler sign"). The incorporation of imaging signs into RadLex
adds to the ontology as a knowledge source, and will allow students and
practitioners of radiology to efficiently retrieve information.
