Combined models of ultrasound velocity and attenuation for predicting trabecular bone strength and mineral density.

Three quantitative ultrasound parameters and their combinations were examined as possible predictors of the bone mineral density and compressive strength of human cancellous bone. Seventy-three trabecular bone cubes obtained from female cadaveric tibiae were measured by quantitative computed tomography. Measurements of the ultrasound velocity, ultrasound attenuation at 0.
