A bone density test is a medical exam that enables the density of the bone to be measured, or more precisely, its mineral content. Low bone density is a very good indicator of fracture risks, whether vertebral compression or femoral neck fractures.

About the Exam
For osteodensitometry, the technique involves emitting x-rays in the direction of a bone, which will partially absorb them. We then measure what remains of the x-rays after they pass through the bone, which provides information about its density.
This exam, which takes approximately 20 minutes, enables osteoporosis to be detected and, therefore, effectively evaluates the risk of fractures.
If you must undergo other exams during the same period, it is essential that you allow time to pass between these and the bone density test.
- Nuclear medicine: wait 7 days
- Fluoroscopy (digestive exam using barium): wait 15 days
- Scan using iodine: wait 7 days
- If you take calcium: stop 48 hours before the exam
Do not undergo this exam if you are pregnant.
Before the bone density test, x-ray images of your lumbar spine will be taken to have an idea of its condition.
Next, you will be directed to the room where our staff will get you settled on the exam table, lying on your back.
The technologist will get you positioned and then the device will slowly move above you.
