The CT scan is the gold standard for investigation of fusion but an X-ray with flexion/extension views can be helpful.
The MRI is used for understanding canal and nerve foramen (see website) size although the CT scan can also be used for this with less detail and resolution. A CT myelogram can be more helpful than a CT scan but requires a spinal injection of dye.
The radiologist’s comment of “very large” spaces most likely means a comment on the graft sizes. Normal graft sizes are 7-9mm but with a corpectomy (removal of some or all of the vertebral body), the graft sizes can increase to 20mm.
