I guess what I’m trying to figure out is if there anyway to tell if a bone graft was ever put in the disc space. Is there a specific color that would appear on a CT-Scan or MRI that would indicate it is a bonegraft or a failed bone graft?
Thank you for the assistance
Many things are placed in the disc space including plastic (PEEK cages), metal (titanium cages), thick bone (fibular head) or iliac crest. Many times, a plate or screws or both are also used. Each has a different appearance on the CT or MRI scans.

I can see the playe and screws and actually one of the top screws appears to be in the spinal canal. I wish I could send you a picture of this MRI. If it is indeed a bone graft then it kind of looks like a worm with thousands of legs and it appears to be broken in half.
Iliac crest allograft (not your own bone) can fracture depending upon the bone density of the graft (taken out of a 36 year old or a 75 year old). If the graft has fractured, it can still fuse but will take as much as 6 months. If it fragments and does not consolidate, you might need a revision surgery (either a posterior fusion or a revision anterior fusion).

Also what would a screw look like on a axial view.
Screws appear as dark “shadows”. Since screws are made of titanium, there is some flair artifact and they appear bigger than they really are. If there is surrounding CSF around the cord, it is unlikely that central canal stenosis is present. The cord can still be dysfunctional if there is angulation of the canal or the cord is draped over some obstruction but that is unlikely.
