Decision Tree classifier for classification of Brain MRI images and texture features

I have applied decision tree classifier using the direct function in MATLAB RegressionTree.fit and predict. I have used texture features and applied for the classification of MRI images. But I am getting very low accuracy that is 60%. What can I do to increase this.

Search the literature for other methods, keep working on your method, hire someone who's done something similar, etc.
