1. A method for data retrieval of a final result list, comprising: analyzing at least one image to detect structures; mapping the detected structures to unique resource identifiers coming from knowledge database; storing the detected structures and the unique resource identifiers as a first semantic annotation; analyzing at least one report to identify a content of a text passage; mapping the text passage to unique resource identifiers coming from the knowledge database; storing a begin and an end of the text passage and the unique resource identifiers as a second semantic annotation; analyzing at the least one image to compute at least one feature; storing the at least one computed feature and an index for fast retrieval; proving an input query describing a search to be executed; forming a first query based on the input query and on additional anatomic information provided by the knowledge database; generating a first result list providing search results of the first query based on the semantic annotations; forming a second query based on the input query and at least one computed feature based on the input query; generating a second result list providing search results of the second query based on the at least one stored computed feature; and aggregating the first result list and the second result list to form a final result list that provides reference to at least one of the at least one image and an image region of the at least one image.
