Which screening test, often called bone densitometry, uses small doses of X-rays to determine the mineral density of a patient's bones?

A) Dual-energy X-ray absorptiometry
B) Radiation
C) Nuclear ventriculography
D) SPECT
E) MUGA scan

Dual-Energy X-Ray Absorptiometry

A method used to assess bone mineral density and body composition by using two different X-ray beams at varying energy levels.

Bone Densitometry

A diagnostic test, often referred to as a DEXA scan, that measures the density and mineral content of bones to assess osteoporosis risk.

Mineral Density

A measure of the concentration of minerals (mainly calcium and phosphorus) in a specific volume of bone, indicating its strength and health.
