Abstract : In this paper, we propose to assess the results obtained by our automatic system for classifying hepatic lesions. Our database contains 107 multi-phase liver nodules from 7 different diagnosis types. As multi-phase scans are not commonly found in Computer Aided Diagnosis systems, an analysis of the potential improvement introduced by working on multiphase versus single portal phase CT acquisitions is made, as well as the comparison of our tool classification results to the ones obtained by two radiologists. Experimental results led to the validation of the method.
