Dear

I am writing to you to see the possibility that you can help me with an investigation related to the use of the 3d Slicer system.

I wanted to know if you know how to delineate lesions (the regions of interest “ROI” of tumor) in MRI automatically and not manually with the 3D Slicer system.

Thank you very much.
