Abstract：Computer aided diagnosis by means of MRI (Magnetic Resonance Imaging) has been
gradually used in staging of cirrhosis. In this paper, MRI is applied in staging of cirrhosis based on MR8
filter banks. A staging system that applies to five sequences of liver MRI, including T1-weighted, T2-
weighted, arterial phase, portal venous phase and equilibrium phase, is structured to improve staging
accuracy. A significant advantage of MR8 filter banks is the rotation invariance. Therefore, MR8 filter
banks are used to extract texture features and to construct statistical histogram of texton. The statistical
histograms are then used to separate the MRI sequences into three stages: normal, early stage and the
middle and advanced stage. The experimental results show that the method employed in this paper has an
excellent performance of accuracy compared with the classic GLCM (Gray Level Co-occurrence Matrix)
method. Especially in T2-weighted sequence and equilibrium phase sequence, the ROI in three stages
of both sequences appears a 100% accuracy. On this basis, the ROI results of the five sequences are
integrated into the final case accuracy results, which is also 100%.
