Couple things:

Continuing to have pain after a fusion is very common. Failed Back Surgery Syndrome can occur in something like 60-70% of the time.

In some smaller hospitals in my area, the radiologist rotate schedules so they may not necessarily have subspecialties as Gary stated above when reading MRIs and CT. Not sure if you are in that type of situation.

Your pain doctor could ask for more specifics on the fusion and the radiologist will amend the report. I do this regularly when I spot something specific in a previous image report and it is not mentioned in the current report.

Most pain doctors in this area will ask for a disk of the images and look at it themselves.
