Hi there! Good to hear from you.
I don't know what a CT will show but I can't imagine much. My CT was clear before I was diagnosed because they thought I had suffered a stroke.
Since the brain lesion that caused the vision loss is (and was) almost 2 cm long and it wasn't visible on the scan, I can't imagine what lesions would.
Maybe they have a CT protocol similar to the MRI protocol for MS that will allow something to show...
Are they doing contrast? I didn't have that and maybe it would make a difference?
I hope Lemtrada is treating you well and it's great to see you back on the board.
CT scan will not show much. The best test is the simple neurological exam. They used it before the MRI was invented. In 1965 they could tell I had brain stem damage from the neurological exam. The majority of MS is gray matter damage which MRIs do not show,
Doc said CT will not show anything because most of my lesions are in the grey area of my brain. Oh well, nice to not know, I guess. Completed Lemtrada in February and feel better except for extreme fatigue
