Hi,

For segmentation and CSF(Cerebrospinal fluid) extraction you can follow similar answer mentioned below, these are based on non-Deep Learning methods. If you want to segment the images and have ground truth labels you can follow 3-D Brain Tumor Segmentation Using Deep Learning.

Hi! Thank you for the answer, however I have already checked these answers and still I haven't found the right answer. That's because I have only a fmri image, without the structural one.
