Bone density test is used to determine whether there is osteoporosis or a pre-stage of it in the skeleton. It is a reliable method for assessing bone strength and the fracture risk caused by osteoporosis. The examination uses X-rays and is therefore not suitable for pregnant women.

The radiologist will provide a report on the examination. The physician who referred you for the examination will inform you of the results and discuss further treatment. Contact your care unit if you do not have a scheduled appointment or call time.
Bone density test is a quick, painless, and safe examination method. It is performed using low-dose X-ray radiation and is therefore not suitable for pregnant women.
The final radiation dose depends on the technique used and the number of images taken. The radiation dose from an X-ray examination and the potential risk from radiation is small.
If you have concerns about radiation, you can always ask for more information from your treating physician or the radiology staff. Information about the effects of radiation and the radiation doses of different examinations can also be found in our Information about radiation section.
