quantitative ultrasound (QUS),

modality employed to measure bone mineral density by ultrasound, applied especially to the calcaneus.

quantitative ultrasound

an ultrasound technique for assessing bone mineral density. Its main advantage is the complete absence of radiation; a disadvantage is the confounding influence of soft tissue.

quantitative ultrasound

Abbreviation: QUS
Measurement of the density of a body tissue, e.g., bone, by determining how rapidly sound travels through the tissue and how different sonic wavelengths are absorbed. QUS is used to diagnose osteopenia and osteoporosis.
