CADx (Computer Diagnostic Assistance) systems for mammographic images as well as MRI images are an effective means for analysis. They allow radiologists to make a selection of relevant and useful information. In addition, with 3D visualization, they offer them a clearer and more precise vision of the information produced. A multimodal fusion was developed in this project. The proposed system is a tool for centralizing information, it allows the improvement the standard process of "screening" by a generally standardized annotation and an encoding of the various anomalies and their characteristic features.
