Abstract

In computer systems aimed at generating and managing reports in radiology dominates the acquisition and storage of information in an open form of textual annotation. A major challenge faced in the development of these systems lies in the inadequacy of environments characterized by standardized interfaces that severely restrict the freedom of physicians in filling their reports, in contrast to the ineffectiveness of open text environments, which restrict a further analysis by computers. This paper aims to propose a methodology for structuring radiological reports from the Hospital das Clínicas da Faculdade de Medicina at Ribeirão Preto aiming in the future to build semi-automatically a report structure that allows knowledge extraction in order to facilitate the activities involved in teaching and researching in this hospital school. The methodology was evaluated on three bases each containing 5000 reports and the results compared with a standard ontology.
