Both technologies assess bone condition, but they answer different clinical questions. Understanding the difference helps a clinic build an effective osteoporosis pathway — and avoid buying the wrong instrument.
DEXA: the diagnostic standard
WHO criteria for osteoporosis are defined for DEXA measurements of the spine and femur. Only axial DEXA provides the T-score on which diagnosis and therapy decisions are based, and it is the method used to monitor treatment. It requires a dedicated room and a trained operator.
Ultrasound: screening without radiation
Quantitative ultrasound measures the speed and attenuation of sound in bone. There is no ionizing radiation, no shielded room and no license requirements — the device works in a GP office, health-check program or pharmacy. Its role is to find patients who need referral to DEXA, not to replace it.
- •Diagnosis and therapy monitoring → axial DEXA
- •Mass screening, mobile programs → ultrasound
- •Optimal pathway: ultrasound screening + DEXA confirmation
