[Ultrasound bone densitometry of os calsis].

In the last couple of years, Ultrasound bone densitometry (QUS: Quantitative ultrasound) have been developed which allow the assessment of fracture risk caused by osteoporosis. QUS are particularly promising since they are simple, inexpensive, portable, non-invasive and they do not subject the patient to any ionising radiation. Additional investigations that assess innovative QUS techniques in well defined research settings are important to determine and utilize the full potential of this technology for the benefit of early detection and monitoring of osteoporosis.
