DPX (DEXA method)

Indication and advantages and disadvantages of DPX and DXA

This type of measurement is regarded as the best method of discovering early loss of bone mass in the spine.

This measurement of the bone density is always recommended for the first examination and in particular for monitoring the development (under therapy).

Advantages: Low radiation exposure

The disadvantage compared to QCT is the restricted evaluation in the case of existing signs of wear of the lumbar spine (serrated spurs) and increased calcification of the small vertebral joints and possibly existing aorta sclerosis. Owing to the changes described with reactive calcification, density values which are to some extent too high can be obtained.

However, in these cases, too, the t value which is described is helpful for enhanced diagnostics.
