The two sets of results are quite different, but as your DEXA is from two years ago, I would think you should wait to compare once you have the next DEXA. I have read the DEXA results can be quite different as well from one machine to another, and one operator to another. Are you having the next DEXA at the same place? REMS is supposed to be more reliable from that perspective. I had a DEXA in November, and I've just had a REMS a couple of weeks ago. The two are not that different, but better results with REMS, and a more positive fracture score. Overall, not huge differences, but I am somewhat relieved that my fracture risk is lower, due to bone strength, not just a measurement of the actual density.
