Examples

  • Bone density scanning, using dual energy absorptiometry (DXA) scan of the axial skeleton (using the lumbar spine and hip), is considered to be the 'gold standard' of diagnostic techniques.

Morphology

absorptiometry = absorption (semi-transparent) = absorb + metry

While 'absorption' and 'metry' are clear components, the specific scientific application is not immediately obvious to all learners.

Etymology

Absorptiometry starts with absorb ('to take in') and ends with -metry ('measure'), the same measuring part you see in thermometer. So absorptiometry is a way to measure how much something 'takes in' or 'soaks up', which is why doctors use it to check things like bone density.
