Bone density is measured using the Dual Energy X-ray Absorptiometry (DEXA) method. This method uses X-rays to determine bone mass, while exposure to radiation is very low.
Osteoporosis, a disease in which there is a calcium insufficiency making the bones thinner and more fragile, is usually tested and monitored with this method. It usually affects menopausal women, but its existence is increasingly detected in men. Nowadays, osteoporosis can, in many cases, be prevented and treated.
The measurements are applied to the spine, hips (each separately and a comparative analysis of both hips), the forearm and the whole body. The method is fast, non-invasive and the measurements are reproducible, enabling monitoring of drug therapy.
Bone density is usually measured:
- In the lumbar spine
- On the hip
