This paper presents our research results obtained within the Cost Effective Health Preservation Consortium Project to apply three different information retrieval techniques to brain computer tomography (CT) image and report retrieval in order to satisfy different information needs. The results are materialised in the NeuRadIR (neuroradiological information retrieval) system, which enables physicians to use medical text and image databases, related to human brain CT, over the Web in order to support diagnosis and patient care. After describing briefly the approaches in image retrieval, the applied retrieval methods are presented. This is followed by the description of the NeuRadIR system. Evaluation results are also reported and discussed.
