Bone density screening in females in climacteric

: Bonestability is not only determined by the content but also by the construction of the mineral part and the biochemical structure. In addition the organic parts are important, too. Result of the measurements shows only the bone-quantity. The development of several measurement techniques (highquality quantitative computertomography [QCT]) allow us diagnoses concerning the bone quality. Single photon absorptionsdensitometry (SPA), DPA (dual photon absorptiometry), DEXA (dual energy X-ray absorptiometry) and QCT (quantitative computertomography, peripher and central) are todays measurement techniques. In the meantime SPA looses the importance, also DPA-method is displaced by DEXA.
