Summary:The invention relates to a system and a method for computer-aided detection (CAD) of aggressive prostate cancers. The automatic diagnosis of aggressive prostate cancers is difficult and methods that work with some MRI scanners do not work as well when implemented on images from different scanners. By studying a data base containing MRI data and biopsy results from 265 patients, acquired by 4 different types of MRI scanners, using machine learning techniques, the inventors established a method for automatically determining the presence of aggressive cancers, this methods showing high sensitivity and specificity when implemented on another database containing MRI data from 270 patients, acquired by different MRI scanners than the first database. The method involves feeding MRI images to a system calculating a score for a portion of the prostate and determines that the portion contains an aggressive cancer based on whether a criterion depending on the score is verified.
