Hello Cheryl,
Not sure I can help much, but when I was diagnosed 12 months ago, I had both bone and kidney biopsies, a full skeletal xray and I think an MRI on the spine, but according to the hospital records, I never had the latter!
Last month I had another full skeletal xray and an MRI on the spine. At my consultant mtg a couple of weeks later, she told me that they can compare the two sets of xrays to investigate any further bone damage, but it wasn’t a NICE requirement to initially have an MRI (at diagnosis) so she said they have nothing to ‘benchmark to’ regarding the spine MRI, but of course now, they have the recent MRI picture to compare with – for future MRIs.
I have no idea about the drug you mentioned.
Not sure I’ve helped much, but very best wishes for the future.
Peter
