About ARRS GoldMiner™

ARRS GoldMiner™ provides instant access to images published in selected peer-reviewed radiology journals. This new, web-based system allows viewers to search for images by findings, anatomy, imaging technique, and patient age and sex.

How It Works

Unlike most internet search engines, ARRS GoldMiner™ understands medical vocabulary. It uses sophisticated techniques from the U.S. National Library of Medicine (part of NIH) to discover medical concepts in free-text figure captions, and uses that information to quickly retrieve relevant images. GoldMiner incorporates standardized vocabularies, such as the Medical Subject Heading (MeSH) terms, which are used to index the medical literature in MEDLINE and PubMed.

ARRS GoldMiner™ recognizes abbreviations, synonyms, and kinds of diseases. Not only does it know that "renal calculi" and "kidney stones" mean the same thing, it knows that renal calculi are a type of kidney disease.

GoldMiner searches by both concepts and keywords. As a result, searches for "renal calculi" and "kidney stones" won't find exactly the same entries. If a figure caption says "stones are seen in the kidney", the words "stones" and "kidney" will be indexed, but not necessarily the concept of kidney stones / renal calculi.

As with a conventional search engine, GoldMiner's search results can depend on the presence of specific words in the figure captions.

Using ARRS GoldMiner™

To find images, enter a search term that describes a disease, imaging finding, or anatomic feature.

You can filter the search results by imaging modality (e.g., "CT"), age, and/or sex — just click on the pull-down menus in the grey bar at the top of the search results page. The selections will indicate the number of images for each selection.

Click on the small "thumbnail" image to open a full-size image on the original journal's web site. You can link to the full text of the article as well — just click on the article's name.
