Abstract: An apparatus is provided that includes a processor and memory storing executable instructions that in response to execution by the processor cause the apparatus to at least perform a number of operations. The apparatus is caused to query a search engine index based upon a user query including a search term, and based upon one or more synonyms of the term. The search engine index is of a database of unstructured, free-text reports, and the search engine index is queried to locate identifiers of image studies associated with reports including the search term or synonym(s). The apparatus may be caused to sort or filter the search results based on patient information from the image studies of the located identifiers, receive user selection of one or more image studies from the search results, and retrieve the selected one or more image studies.
