What is Bone Densitomery?

The DEXA bone densitometer is used to measure a patient’s Bone Mineral Density (BMD). The DEXA scanner is considered the gold standard among health care professionals for measuring body fat, lean mass and bone mineral content and assessing osteoporosis and risk of future fracture. It is a table scanner that uses two energy levels of low-dose x-ray to quickly measure the bone density of several skeletal sites including the wrist, hips and spine.

Is Bone Densitomery safe?

The procedure is completely non-invasive and exposure to radiation is small, equaling 1/10th of the amount received from a chest X-ray, or the amount of naturally occurring background radiation encountered in one week. However, because of the risks of radiation exposure to the fetus, pregnant women are advised to avoid this procedure.

How do I prepare for my scan?

There is no need for any special preparation, you may eat normally and you can take the scan fully clothed. However, it is recommended that you do not take calcium supplements 12 hours before your study.

On the day of your appointment you will need to arrive about 15 minutes before your appointment time.

What can I expect during my scan?

You will be asked to lie still on a padded table, and breathe normally. It is an open scan, so there is no need to worry about closed spaces. The radiographer may place special pads underneath or alongside your body to ensure proper positioning and comfort. The scan lasts for several minutes whilst the arm of the machine passes over the region of your body being scanned.

When will I get the results?

The results of your scan will be sent to your referring doctor/consultant within 24 hours of your exam. Your report and images will include a summary of the radiologist’s findings and recommendations for further follow-up.

Chaperone service

All patients are entitled to have a chaperone present for any consultation, examination or procedure where they feel one is required.

This chaperone may be a family member or friend. On occasions it may be necessary for a formal chaperone to be present, ie a trained member of staff. Please let us know prior to your appointment if you require a chaperone.

Any other queries?

If you have any other questions, worries or doubts do not hesitate to ask one of our staff. We want you to feel as comfortable as possible.
