In this paper, we propose a system for the automated classification of liver focal lesions of Computer Tomography (CT) images based on a multi-phase examination protocol. Many visual features are first extracted from the CT-scans and then labelled by a Support Vector Machine classifier. Our dataset contains 95 lesions from 5 types: cysts, adenomas, haemangiomas, hepatocellular carcinomas and metastasis. A Leave-One-Out cross-validation technique allows for classification evaluation. The multi-phase results are compared to the single-phase ones and show a significant improvement, in particular on hypervascular lesions.
