@katgirl - "True Bone Density" held the REMS event (using Echolight EchoS equipment and their supposedly trained technician) at Osteostrong in Eden Prairie MN. They provided an FAQ that stated no refunds and that results vs. Dexa may vary significantly (which they sure did!). So no, I did not contact either True Bone Density or Osteostrong afterward. But maybe I will. Some of the advantages of REMS are the portability of the equipment (can be brought to various sites) and that the results don't vary as much as Dexascan (which can vary based on the device calibration and which tech did the scan) - so I thought it would be a fairly accurate REMS test regardless of where it was done. But my experience with REMS was that the result (a green light for fragility and NO Osteoporosis) was patently unbelievable: how could a person who has had a dozen bone fractures (granted, never my spine or hip), had Osteoporosis for 15 years (dx at 48), and has a current Dexa T-score of -4.3 (L1-L4)... not even have Osteoporosis? Not credible.
