Hi, CAllallo,
When I retired, I was a year and a half away from Medicare. So went to a different medical group during that time until I could go back to my old one. Well, I was due for my DEXA. They did it at the new facility. But they also told me it could not be compared to my old scans because they use a "different" DEXA scanner. Apparently, you need to stay with the same brand (?) of scanner to be able to compare old files.
