Alia,
do you know the rates for heart and liver? her T2* I mean for heart and liver? because "some in the heart and some in the liver" that you say, is so vague.If you know rates, please tell us to get the right picture of Sara. Generally speaking, ferriprox goes for the heart while desferal and exjade go for liver. So if there is iron in her liver, desferal or exjade are needed. Of course, I am not sure if she can take desferal in her age. What does her doctor say about that?
