A bone density test, or DEXA (dual energy x-ray absorptiometry) scan, is designed to check for osteoporosis, a disease that occurs when bones become thin and weak. Osteoporosis occurs when bones lose calcium and other minerals that keep them strong. Osteoporosis most commonly affects women after menopause and continues to progress over time and can result in serious fractures if not treated.  Bone densitometry is a simple and painless test that uses special x-rays to measure the strength of your bones and determines the risk  of fracture. 

Bone density testing may be recommended if any of the following are true:

If you have experienced a fracture after only mild trauma If you have a thyroid condition Have had an x-ray with evidence of fracture or other signs of osteoporosis Are a post-menopausal woman not taking estrogen Have a personal or maternal history of hip fracture or smoking Are a man with clinical conditions associated with bone loss Use medications that are known to cause bone loss Have type 1 diabetes, liver, kidney or family history of osteoporosis

How to prepare for my Bone Density test @ SRC?

You can eat normally on the day of your exam, but don’t take your calcium supplements for at least 24 hours before your test.  Wear comfortable loose fitting clothes.  Avoid garments that have metal such as zippers, belts or buttons.  Your bone density test only takes 20-30 minutes.  You will lie on a padded table as the scanner arm passes over you.

If you recently had an examination that involved injected contrast materials like a CT scan please inform your physician, you must wait 10-14 days before your bone density test is performed.  If you are a woman and there is a possibility you are pregnant, you should inform your physician or the technologist.
