Similar but different. I had a DEXA in April, L1-4 was -3.2, it had been -2.9 for the last 5 years, my femoral neck was unchanged at -1.7. I was very surprised by the decrease in my spine. The technologist ran the analysis and said, “everything looks good, looks about the same”, but didn’t say what the t-score was, then he said “I’m just going to run the analysis again” and I ended up with the -3.2!
I had a REMS Echolight in June, my spine on that was -1.7, big difference. My hip scores were very similar to the DEXA. The physician who did the REMS test talked a lot about the test, how it differs from à DEXA , and was very confident in the results it produced for me. He told me I didn’t need meds and I could come back in 2 or 3 years if I wanted to have another scan. However he didn’t seem to have a good explanation for the discrepancy between the two spine results!
