SVMIC Diagnostic Radiology: Interpreting the Risks

Benefits & Drawbacks of a Standardized RadLex

Radiology Lexicon (RadLex) is a proposed unified language

of radiology terms for standardized indexing and retrieval of
radiology information resources that was developed by the

Radiological Society of North America.

The advertised features of RadLex include the following:

• Imaging protocols, picture archiving, and communication

system display formats can be specified by using vendor-
independent language.

• Speech recognition can be improved by including

descriptions linked to the body site imaged and the
modality used.

• Decision support tools can automatically retrieve case-

relevant information in real time (e.g. checklists of image

features to be sought; information from PubMed, the
internet, and proprietary decision of support databases).

Disadvantages include the following:

• Although it is an attractive project, the enormity of the
undertaking makes universal adoption difficult.

• Standardized reporting templates and RadLex are “best

practices” initiatives but have not been nationally accepted
and cannot be considered the standard of care.

• Radiologists develop “styles of dictation” over several years

of training. Adopting may result in a learning curve that
compromises the accuracy of the reports.
