Let me tell you, folks, we’ve got something **incredible** here, absolutely fantastic. We took a look, a big look, at how we can figure out bone health, the best way, believe me. We’re talking about bone mineral density (BMD), very important, and we’re using something called dual-energy x-ray absorptiometry (DEXA) – top of the line, really top. But that’s not all, we’re also looking at Hounsfield units (HU) in the lumbar spine, very specific, very accurate.

We did this huge study, huge, on 712 lumbar vertebrae. We’re not messing around. We excluded the bad ones, the ones with issues, because we want the best data, only the best. And guess what? We found that the HU values, when you look at them in the right places, they tell us a lot about bone health, a lot. More than ever before.

The BMD and HU, they go up from L1 to L4, showing us clear, beautiful patterns. But here’s the kicker – the HU values in these special areas we’re looking at, they’re even better at showing us what’s going on with bone health. They’re predicting osteoporosis like nobody’s business, with incredible accuracy. We’re talking high sensitivity, high specificity – it’s fantastic.

This, my friends, is a game-changer. We’re introducing a novel approach, a brilliant approach, to assess bone health at the lumbar spine. The correlation? Strong, very strong. We can now predict osteoporosis with this method, and it’s going to be huge. Absolutely huge.
