Hello,
Yes, your brain anatomy can be visualized on an
MRI scan. A CAT
scan can visualize skull fractures, tumors, etc., but an MRI shows your underlying vascular structures of the brain.
I, too, have suffered with trigeminal neuralgia, which has been controlled with Neurontin and also steroid injection blocks in head and neck.
I hope this has been of some help to you.....Take care.....
