Bone Densitometry - Dual Energy X-ray Absorptiometry (BMD-DEXA) is used to measure bone mineral density (BMD). The technique uses very low dose x-rays and is a safe and painless procedure. The entire procedure lasts approximately 20 minutes.
Low bone density or osteoporosis is a major indicator of fracture risk and is common, particularly in women following menopause. Loss of bone density may also be accelerated in conditions affecting the liver and thyroid gland and by certain medications, in particular, steroids. Measurement of the spine and hip is routinely performed and measurement of the forearm may also be undertaken, if required.
All appointments will be scheduled after receiving a requisition from you physician or patient care provider.
For this exam, you will lie on a padded BMD table for a few minutes while the scanner – a mechanical arm-like device – passes over your body. It will not touch you. There is radiation emitted during this exam and the exposure during a BMD is commonly about 1/10th of the amount emitted for a chest x-ray.
The exam usually takes about 20 minutes to complete. The radiologist will interpret the exam and the results will be sent to your physician within 2-3 working days.
This service is provided Monday through Friday and at this time this service is not available on weekends.
