Just to let you know that I've just had a scan for this. I dont know whether this is because of blood tests or because people with RA may be more susceptible to it (which is the case apparently).. ANyway on the lines of what I said in Tilda's blog I tend to take what's offered and have just come back from having the scan. They just make you lie down on a bench and this thing which sounds like a photocopier whirrs for a few minutes. you have to stay still - which isnt easy! I had to fill in a questionnaire about what I eat - how much milk,. eggs, cheese in particular. Anyway that's now done and I await the results. But just thought you might like to know that this is on offer. At least here it is. Better than having brittle bones as you can do things to prevent it.
