Bone ultrasonometry measurements during pregnancy.

Purpose: During pregnancy we can have changes of the calcium metabolism that can determine a loss of bone mass. Some studies used single-photon absorptiometry (SPA) or dual-energy X-ray absorptiometry, but these exams are inadvisable in pregnancy for the teratogenic effects on the fetus. We used quantitative ultrasonometry (QUS).
