OBJECTIVE: To make a software available for training professionals in the interpretation of mammography images on digital systems. MATERIALS AND METHODS: The software was developed in Delphi and linked to a Interbase database to store mammographic images in association with the BI-RADS® category results. Images were previously qualified and digitized using a Lumiscan 75 laser scanner. Training is done on 18 × 24 cm images displayed on a 17² commercial monitor. The software allows displaying of each breast view individually, medial-lateral oblique and cranial-caudal views, or four images simultaneously. The user selects an exam from the database and makes a diagnosis classifying the image into BI-RADS® categories. At the end of the process, the software compares the user's interpretation with the data stored in the database and than yields scores. RESULTS: The user becomes familiar with digital systems, images interpretation using BI-RADS® categories and with the quality of the image generating process regarding the detection of fibers and microcalcifications. CONCLUSION: The software is available at "Universidade Federal de São Paulo", São Paulo, Brazil, intranet and is a valuable tool for training professionals interested in digital systems.

This paper describes the implementation of a computational scheme in the homepage of the Laboratory of Images Analysis and Digitilization, at the Department of Electrical Engineering of the "Escola de Engenharia de São Carlos -- Universidade de São Paulo", São Carlos, SP, Brazil. This computational scheme was designed to provide an interactive tool for the remote user to generate reports and analyze mammography images via network, allowing immediate assessment of the results. The scheme was developed by inserting a bank of selected digitilized mammography images that are linked to a database containing the reports provided by radiologists. Since this process is intended to be used for training in diagnostic evaluation in mammography, a report given by a specialist is provided at the end of each evaluation for comparison with the user's report as well as the percentage of correct statements of the user. This scheme, called "Laudos Online", is intended to be used as a remote learning tool that allows the user to improve his knowledge on mammography.
