Glossary of radiological bone parameters.

Bone parameters	Unit	Definition
Bone Mineral Content (BMC)	G	Sum of all skeletal tissue within the body measured by the densitometer
Areal Bone Mineral Density (aBMD)	g/cm2	Mineral mass of bone per unit area of the two-dimensional projection image
Bone mineral apparent density (BMAD)	g/cm3	Volumetric density (derived from the formula BMD/√ bone area); less dependent on bone size and body stature
Volumetric Bone Mineral Density (vBMD)	g/cm3	Cortical or trabecular density
