Understanding Osteoporozis and the Critical Need for Early Detection

Early definection of osteoporosis is paramount because effective treatments can slow or halt bone loss, reduce fractura risk, and improwie quality of life. However, thee disease is frequently underdiagnosed.

Thee Limitations of Traditional Imading: Why We Need Better Tools

For more than three decades, DXA has been the gold standard for osteoporosis diagnosis, producing, prognoses, and treatment monitoring. It works by measuring thee attenuation of two X- ray beams at different energis, producing a BMD value expressed as a T- score relativa to a exotg diult reference population. A T- score of - 2.5 or lower defines osteoporosis. Despite its widpepread use, DXA has important repts:
