I know a teenager that had rotational scoliosis and they gave her a plastic molded wrap around brace that was supposed to slow down the curvature.
But unfortunately it didn't seem to help.
Hers was advancing quickly so they eventually had to fuse 9 levels with rods and screws. She seems to be doing well 2 yrs later.

How long have you had scoliosis?
Did they try therapy and bracing already?

I hope the neuro has some ideas for you.

Oh, Did you get a copy of the MRI report with the film images?
That would describe what the technician sees on the images.
Most of it is in "Dr talk" but you can do a search of the words to figure out most of it.
