Patient information Dual-energy X-ray Absorptiometry (DXA)

How does it work?

DXA stands for Dual-energy X-ray Absorptiometry. This diagnostic method is considered by specialists to be the most precise procedure available for recognizing osteoporosis as early as possible. The procedure involves releasing two low-energy X-rays of differing intensity into the relevant section of the skeleton (e.g. the lumbar spinal column or the neck of the femur). Through this method, the share of radiation absorbed by soft tissues can be subtracted from the portion absorbed by bones – thus allowing specialists to calculate bone density.

When do we need to use DXA?

By measuring bone density, a DXA examination allows specialists to identify osteoporosis. It is the only diagnostic technology for measuring bone density  now recommended by the DGO (the German Association for Osteology). Osteoporosis is the name of a condition in which bones progressively lose their mineral content. The ailment usually affects older patients (with women being at least twice as likely to be affected as men). It is a common problem for older people, making them more prone to bone breakages – though young people can also be affected by it as a result of calcium or vitamin D deficiency, or due to other diseases.

How is the procedure carried out?

Measurements of bone mass are carried out in our clinic using cutting-edge devices that emit extremely low-intensity X-rays. As you lie comfortably on the examination bench, the X-ray scanner moves around your lumbar spinal region or the neck of your femur. The procedure takes about 10 minutes.
