Bone Mineral Density Measurement by Dual-Energy X-Ray Absorptiometry (DXA) with Risedronate Treatment Monitoring
This test measures how much calcium and other minerals are in your bones using X-rays. It helps assess bone strength and monitor changes over time, especially if you’re taking medications like risedronate for osteoporosis.
["A DXA scan helps track bone health and effectiveness of treatments for conditions like osteoporosis."]

Why This Test Is Done
Your healthcare provider may order this test if you have a higher risk of osteoporosis, have been diagnosed with the condition, or are taking medications like risedronate to prevent bone loss. It’s also used to check if your treatment is working as intended.
What to Expect Before the Test
No special preparation is needed, but you may be asked to remove jewelry, clothing with metal, or any other items that could interfere with the scan. Wear comfortable clothing and avoid wearing a bra with underwire.
During the Test
You’ll stand still on a padded table while a machine takes precise X-ray images of specific bone areas, usually the hips and spine. The process is quick and painless, but you may feel a slight sensation of cold from the X-ray beam.
What the Results Mean
Results are expressed in terms of bone mineral density (BMD) compared to a healthy young adult. Lower BMD values indicate weaker bones, which may signal osteoporosis or other bone-related issues. Your provider will interpret these results in the context of your medical history and treatment plan.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
Short name
DXA Bone Density Scan (with Bisphosphonate Monitoring)
