I had a REMS scan last month (it was offered at an Osteostrong location in Minnesota; I do not do Osteostrong and don't intend to - I lift free weights with a trainer, and walk daily). My experience may well not be representative at all, but I found REMS to be a joke and a waste of $275 (not covered by insurance). The results were so unbelievable (I no longer even had osteoporosis! my fracture risk was in the green zone! 😂) that I immediately scheduled a Dexascan and sure enough, per the Dexa, I am still T -4.3 (and note that I've had osteoporosis for 15 years since age 48 and have fractured many bones, including four wrist fractures, a leg, a foot, etc). Note that the REMS was also PAINFUL, which surprised me. The tech said "there will be some pressure" as she shoved the wand so hard under my ribs (and held it there) that tears sprung to my eyes and I wondered if I might actually fracture a rib. That was unexpected. The area hurt for a couple days afterward. I will never have another REMS.
