A database of differential-diagnosis listings ("gamuts") in the domain of gastrointestinal radiology has been developed as part of an open, Semantic Web-based knowledge resource for the radiology community. We sought to make that knowledge available through an interactive web site for education and clinical decision support.

An interactive, hyperlinked, and illustrated reference web site has been developed to present information from a knowledge base of “gamuts” in gastrointestinal radiology. The site is freely available as a resource for education and clinical decision support.

The Gamuts web site provides an interactive reference to comprehensive differential diagnosis information. One can easily navigate to specific diseases or imaging observations, and follow hyperlinks between related terms. The web pages are generated on demand from a database, so the site’s knowledge can be updated continually. Related images from peer-reviewed journals are presented automaticlaly. The current knowledge model, which is limited to the domain of gastrointestinal radiology, provides a model for expansion of the site to accommodate the entire spectrum of radiology.

The Gamuts web site (www.gamuts.net) provides an interactive means of displaying differential-diagnosis information about more than 3,300 diseases and imaging observations in the domain of gastrointestinal radiology. As a reference source for our knowledge base, the web version of a well-recognized “Gamuts in Radiology” text was selected; the content of that reference was edited extensively to normalize and disambiguate the terms. Gamuts are grouped by topic (Esophagus, Stomach, Liver, etc.) or can be selected by text search. Each of the items that appears in a gamut is hyperlinked, which allows one to traverse the network of concepts. For example, the gamut for achalasia includes Chagas disease as a cause; one can follow that hyperlink to view all of the gamuts in which Chagas disease occurs, and follow those hyperlinks as desired. The reference is illustrated by images and their captions from peer-reviewed journals, retrieved dynamically by a biomedical image search engine (ARRS GoldMiner®).
