As we age, our bone structure may weaken. This is especially true in postmenopausal women. A Bone Density Scan, also called Dual-Energy X-ray Absorptiometry (DXA), is a specialized X-ray test that uses a very small dose of ionizing radiation to provide information in order to measure bone loss. Its most common uses are to diagnose osteoporosis, to measure bone loss treatment results or to determine future risks for fractures.
Why would my physician recommend a Bone Density Scan (DXA)?
Your physician may recommend a Bone Density Scan (DXA) if you have symptoms of osteoporosis, are being treated for osteoporosis or to assess your risk for developing bone fractures. It is typically recommended for women who are post-menopausal or have conditions associated with bone loss. It may also be recommended for men or children who have certain risk factors, but this is less common.
How does a Bone Density Scan (DXA) work?
The DXA machine sends low-dose X-rays from two different sources through the bones being examined. We then measure the amount of X-rays that get through. The denser the bone, the less X-rays get through to the detector. Two sources are used for increased accuracy. Once the X-rays are measured, a computer calculates a score based on the average density (based on two scores) of the bone. These scores are calculated and reported based on how you compare to the average scores of a young, normal score and to those of your peers to determine your bone loss and risk of fracture.
What should I expect during a Bone Density Scan?
The DXA Scan is a relatively quick and completely painless procedure. During the procedure, you will lie on a padded table. You will be positioned to scan the lower spine, hip and/or forearm. Once positioned, a camera (detector) will pass over the area being tested and capture images. It is important that you remain still while the images are being taken. In addition to the physical tests that are performed, you will be asked medical history questions that will help determine if you have medical conditions or take certain medications that may increase or decrease your risk of a fracture. The results of the test will help predict your risks for hip fracture.
What should I expect after the procedure?
Once the exam is complete, you may resume your normal activity level. Our Radiologist will analyze the images and forward a report to your physician or specialist who will discuss the results with you.

Cheryl PI've been a patient of Fairfax Radiological Consultants for years. My most recent experience was pleasant. I had a Mammogram and bone density test done within the same day. The receptionist was very friendly, receptive and efficient, as were the technicians. The wait time was minimal. I hope to remain a patient with Fairfax Radiological Consultants and would highly recommend your services to anyone.
