Hi Harri, welcome... I'm not sure I understand your question, and if you could provide more details that would be great. Are you saying that only your hip was scanned and not the spine? When a DXA is done they scan both hip and spine and sometimes the wrist, so I don't understand why the spine would have been left out. If this is the case (spine wasn't scanned) then that could explain why a second one would be done, but this is so unusual for a DXA scan. You need to scan both areas, and then the Dr. will use the lowest score of the two as your diagnosis. Could you let us know if just the hip was scanned and why, and what your T-score was. If your hip score is good (in the normal range) and not spine scan was done, you could have a very different score there compared to the hip.

If there is some other explanation please let us know, since this doesn't make a lot of sense.

As you probably know, here's the World Health Orgs definition of T-scores:

Normal bone: Any number above -1.0

Osteopenia: Any number between -1.0 and -2.5

Osteoporosis: Any number at or below -2.5

If for some reason your spine wasn't scanned then this could explain having another, but I've never heard of this done, unless you have had surgery in the lumbar area of the spine and have rods/screws which can over-estimate the score (make it look better than it really is).  The only other thing I can think of was that a VFA (vertebral fracture assesment) wasn't done, and maybe the Dr. wants to add that to the scan to see if you have any new/old fractures in the spinal area.  This test is usually done at the same time as a DXA, but maybe it was left out, but that's just a guess.

Please provide more info, if you can, so we can figure this out.

Good luck...
