Low or very low Z-scores should trigger additional evaluations. Interpretation of DXA scan results should be done within the context of other relevant clinical information. Even children without low Z-scores may be not be achieving their genetic potential for bone mass....
A DXA body density scan produces quantitative data, including clinically BMD, T-score, and Z-score. DXA readers will typically dictate these values to a report along with an interpretation. The dictation process is a source of error. Research has foundspeech recognition software error rates of ...

7 However, factors like measurement precision and rate of change in BMD must be considered for accurate interpretation at different measurement sites and with different populations. The precision error of DXA measurements is important to differentiating between measurement error and genuine bone changes.8...
However, because BMD changes depending on the progression of osteosclerosis due to degenerative changes or vascular calcification and the degree of fat, careful interpretation of DXA is required [6–8]. This tendency is higher in the lumbar spine, which is examined through the abdomen; therefore,...
Results from CT and MRI imaging are consistent with these findings. It is clear that BMD accuracy errors have a clinically important effect on DXA scan interpretation and may cause T-score values to significantly misrepresent patients' true bone status. (1) Svendsen et al. J Bone Miner Res ...

[54]. For vertebral deformity severity stratification, Genant SQ has the distinct advantage of overcoming the above constraint and allowing interpretation of follow-up radiographs as it has the capability to assess delta change in vertebral height [54]. The key to the ABQ method proposed by Jiang...
Clinicians and DXA providers must be familiar with the scientific rationale and procedures involved in measurement science to obtain accurate and reproducible results. Their importance is critical to maximise the value of scan acquisition and interpretation. Scanning individual patients, with different needs...
