What is a Bone Density Study?
A bone density study measures the calcium content (density) of your bones. A scanner that emits tiny amounts of radiation is used for this exam. Scans of your low back, hip, or forearm are most often taken. You are having this exam because may may be at risk for osteoporosis (loss of bone mass). This exam can also show whether your medications are slowing down bone loss. BEFORE YOUR EXAM Prepare for your exam as instructed. It may be canceled if you don’t. Wear clothing with no metal closures, such as zippers. You may have to remove your watch or other metal items that can affect exam results. You may be asked to wear a gown. This test takes just 15 to 20 minutes. But you’ll need to allow extra time to check in.
