[Dual photon absorptiometry in algodystrophy]

Biphotonic absorptiometry has begun to demonstrate its usefulness in the field of osteoporosis. In algodystrophy, the radiology and the degree of isotopic fixation suggest a bone disorder, although both techniques are unable to objectively quantify it. Biphotonic absorption is an scanning technique which allows the quantification of bone demineralization in the segment affected by algodystrophy and its evolutive follow-up.
