If your question is "which class does a particular feature belong to?", then this might not be the best place to ask. Your professor/advisor/boss/ or someone with a background in radiology might be able to guide you better.

The Stats Toolbox would be useful for this. It has a function called CLASSIFY. You must however know which segmented part is which class to Train. You can then test the classifier on the other segments which were not used for training and compare against their known answers.

If you do not know which segment belongs to which class, you can then use KMEANS with k = 3.

Hope this helps.
