Hi all, (it's gadolinium not barium)

I have an MRI of spine in the morning and the rheum has requested I have gadolinium iv first for it. This I understand is an IV solution of gadolinium which goes round parts of your body to make the scan easier to read.
Does anyone know if there are issues with this for us with sfn /autonomic neuropathy? Kind of want this if it will show greater detail of the Spinal damage/inflammation I have.
