Paper Abstract

Despites many limitations, liver biopsy remains the gold standard method for grading and staging liver biopsy. Several modalities have been developed for a non invasive assessment of liver diseases. Real-time elastography may constitute a true alternative to liver biopsy by providing an image of tissular elasticity distribution correlated to the fibrosis grade. In this paper, we investigate a new approach for the assessment of liver fibrosis by the classification of fibrosis morphometry. Multiresolution histogram, based on a combination of intensity and texture features, has been tested as feature space. Thus, the ability of such multiresolution histograms to discriminate fibrosis grade has been proven. The results have been tested on seventeen patients that underwent a real time elastography and FibroScan examination.
