Comparison of DXA scanners shows variability in BMD and T-scores, indicating potential clinical implications.
DXA scanners showed substantial concordance in T-score and BMD, particularly in femoral measurements. The slight differences between these measurements did not have a major effect on OP diagnosis. Greater variability in lumbar spine results warrants caution. Further studies should aim to minimize inter-scanner differences and assess their long-term clinical implications.
