Bone Densitometry (DEXA Scan)

Bone densitometry, also known as a DEXA scan (Dual-Energy X-ray Absorptiometry), is a specialized imaging technique used to measure bone mineral density (BMD). It is the most accurate method for diagnosing osteoporosis, a condition characterized by weakened bones that are more prone to fractures. The scan helps assess bone health, detect bone loss, and evaluate the risk of fractures.

Benefits of a DEXA Scan

• Accurate Measurement : Provides precise measurements of bone density and can identify osteoporosis at an early stage.
• Non-Invasive and Quick : The procedure is painless and takes about 10-20 minutes to complete.
• Low Radiation Exposure : Uses much lower levels of radiation than standard X-ray tests.
• Helps in Treatment Decisions : Results can guide doctors in prescribing appropriate treatments to improve bone health.

Preparing for a DEXA Scan

Preparation for a DEXA scan is minimal :

• Avoid Calcium Supplements : Do not take calcium supplements for at least 24 hours before the test.
• Wear Comfortable Clothing : Avoid clothing with metal zippers, belts, or buttons that could interfere with the scan.
• Inform the Technician if You’re Pregnant : Though the radiation dose is low, the scan is usually avoided during pregnancy unless absolutely necessary.
