I know exactly what you're talking about!!!!!!
I did an MRI recently...after xrays and a nuclear bone scan...both of which my doc said showed no changes, therefore my insurance would not consider paying for Enbrel...my doc sent me for a 'pelvic exam', the insurance company put up a fight over that, but I went in....and the radiologist said that a pelvic exam would not cover the sacrolaic joints or lower spine that my doc wanted covered, and that MRIs do not show the inflamation my doc is looking for...this was all to appease the insurance company, and instead of sitting under the magnet for forty minutes, it was two hours!!!!!!! I nearly died in there, my legs and arms went numb, and my hips hurt so bad that when I was finally done I couldn't get up off the table...I would not wish that on my worst enemy...well, ok, my worst...
I agree with everyone here, just because there is no fusion to see on film, does not mean you don't have inflamatory activity for years on end....PAINful inflamation...that must be STOPPED....
Hang in there, keep us posted, you rock...
