I have never heard of this before, however, I am going to recommend this to my doctor when I see him, to see if I can have this type of scan rather than a bone density test. Unfortunately, Reclast is probably not an option again because they believe me to be allergic to it. I really need to find something that can increase my numbers and slow down the hypercalcemia and severe osteoporosis. This sounds like a good option to see a better view of the integrity of the bone.
