Apparently this was done because air captures less X-rays than CSF and thus creates more contrast with brain tissue compared to the cerebrospinal fluid.

Unfortunately this was pretty painful and uncomfortable.

Well that just sounds awful. What’s not clear is how CSF gets back in there. Do they replace it or let the body figure it out on its own?

Not sure to be honest but i’m guessing that enough would be left and that the air would resorb and new CSF would be made in the ventricles.
