Bone density scan
A bone density scan, also called bone densitometry, is a safe, painless X-ray examination that makes it possible to measure the density of your bones and determine whether you have osteoporosis: a disease characterized by a decrease in bone mineral density.
The risk factors for osteoporosis are:
- smoking
- high intake of alcohol and caffeine
- a sedentary lifestyle
- a diet low in calcium and vitamin D
- a family history of osteoporosis
- a history of fracture after minor traumas
- low body weight or weight loss
Bone density scan examination procedure
For the examination procedure, you will be asked:
- to change into a hospital gown and remove your jewellery and other metal objects, which can interfere with image quality
- to lay comfortably on an examination table
- to remain still while an X-ray machine will move slowly above your body and take images (e.g. hips, spine, forearm) that will be analyzed by a technologist to determine if you have osteoporosis.. The results will be determined by a radiologist and sent to your healthcare professional. The examination may be complemented with X-rays of the spinal column, if needed.
Please note that the total duration of your visit for this examination can be between 30 and 60 minutes, even though the examination procedure itself will only last approximately 20 minutes.
Preparing for the bone density scan examination
Before the examination, we will ask you to inform your healthcare professional and the technologist at our clinic if there is any chance that you may be pregnant.
Here are the steps to follow to properly prepare for the examination
For the 14 days before your appointment, it is important to avoid any X-rays and nuclear medicine tests that may involve contrast agents.
For the 48 hours before the examination, we will ask you to stop taking calcium tablets or vitamins that contain calcium (you can, however, drink and eat foods that contain calcium).
On the day of the examination, you can eat normal meals before the examination.
A medical prescription is required to perform this examination. The cost of this examination is covered by the Régie de l'assurance maladie du Québec (RAMQ) at Imagix when prescribed by a physician.*
