I used to live in South Australia , and in 2010 I had a C2-3 cervical fusion, very successful with Dr Cindy Molloy with whom I am having difficulty communicating, My neurosurgeon here in the UK needs to do a Lumbar/ sacral MRI . I need to know if the C2-3 op is likely to produce a problem. I do not know the composition of any components she used
Dear patient The compatibility of MRI depends on material of fusion. You can get plain X-Ray of cervical spine that would let you know composition, and then you can plan your MRI of spine accordingly.  Hope this satisfies your answer
