Abstract:
Objective To analyze magnetic resonance images of medulloblastomas and ependymomas by texture analysis method, and evaluate the texture characteristics of two tumors by support vector machine (SVM).Methods 58 tumors were analyzed retro-spectively,including 31 medulloblastomas and 27 ependymomas,which had been confirmed with operation and pathology.Texture analysis was performed onthese tumors.Results The 5 texture parameters extracted from the gray level co-occurrence matrix and at least 3 parameters which had statistical significance between the two different classes of data sets(P<0.05).For all data sets,the variance parameters of gray value of ROI region have statistical significance.The accuracy of SVM test was (86.15±4.16)%,which had remarkable significance between the ependymomas and medulloblastomas.Conclusion The analysis of texture features can pro-vide a lot of quantitative information,and can be a potential method for the differential diagnosis of medulloblastomas and ependy-momas.
