Abstract
Laterality is an important anatomic directional property indicating the sidedness of body structures, diseases, and procedures. Errors in laterality could have catastrophic consequences in patient care. In this paper, we investigate how different biomedical terminologies organize terms indicating laterality. We leverage the Unified Medical Language System (UMLS) to identify lateral terms in different terminologies. For each lateral term, we attempt to obtain other matched lateral terms and further analyze how they are interrelated. Our results indicated that only 1.68% of the matched lateral term-pairs are hierarchically related. It was also seen that 44.24% of matched-pairs were siblings. We found that in SNOMED CT, bilateral concepts were hierarchically related to both left and right lateral concepts different to most other terminologies. Further investigation revealed that the likely causes for these relations are how the logical definitions of SNOMED CT concepts are arranged.
