I don't know anything about these specific problems but would just add that another advantage of MRI over CT is the lack of radiation exposure. CT gives quite a high dose. MRI doesn't involve any ionising radiation. Also worth adding that bone problems can be due to mineral loss, which many of us suffer from (they tend to be lost in urine). I have been supplementing bone minerals for over 3 years and my bones and teeth seem stronger now. It may be worth getting your blood mineral levels checked.
