How does one get an accurate DEXA Scan?
How does one get an accurate(valid) Dexa Scan after having spinal fusion with metal fixation? Why bother doing the exam when the results reads, "This result is in valid because patient has metal fixation of the spine." I was under the impression that there was an alternate technique or study that could give a bone density result that would mean something. And, I thought my physician had ordered that special technique. ?? Anyone know more about the way to get a bone density assessment that means something, following spinal fusion surgery with fixation?

I have metal in my lumbar spine and I don't recall the tech saying that there was that kind of result. They wouldn't even schedule them if that was the case. Mine was done at Mayo research FWIW.
amkie, usually they image the wrist or ankle, forearm of hip. Bone Scintigraphy, CT or MRI can assess union or nonunion of the implant. The hip measurement should be accurate.
