Dexa Scan – What You Need to Know

What is a Dexa Scan or Bone Density Test?

A Dexa scan or bone density test is a medical examination used to evaluate the strength of bones and check for low bone density. Your doctor may recommend this test if there is concern about your bone density due to age, lack of vitamin D, cancer treatment, or certain medications.

What are the Risk Factors for Low Bone Density?

Age, low calcium and vitamin D diet, alcohol consumption, smoking, inactivity, and the intake of medications with high dosages are some of the risk factors for low bone density.

Who Should Take a Dexa Scan?

A Dexa scan is typically recommended for people over the age of 50, or for those with conditions such as Cushing’s disease, rheumatoid arthritis, hyperthyroidism, chronic inflammatory conditions, and fragility fractures.

How Should I Prepare for a Dexa Scan?

No special preparations are required for a Dexa scan. You can continue with your normal diet and activities before the test. You should avoid taking calcium supplements for 24 hours before the scan.

How is the Procedure Performed?

During a Dexa scan, you lie down on a table while an imaging arm moves over the body part being examined. A beam of low-dose energy is passed into your body to capture images of your bones and determine their density. The procedure takes about 20 minutes.

What are the Risks Involved in a Dexa Scan?

The Dexa scan uses a minimal amount of radiation, which is not harmful. However, repeated scans may increase the risk of developing cancer. Other than this, there are no known risks or complications associated with the procedure.
