Dexa Scan or Bone Mineral Density (BMD) is an examination performed to check
the strength of your bone. The test utilizes X-rays for measuring calcium grams
and some other minerals in bone segment. If your bone density is lower than
normal for your age, it indicates a risk for osteoporosis and bone fractures.
Bone density test provides info about your bone health. It is also used to diagnose patients suspected of osteoporosis. Patients who undergo orthopaedic treatment for bone disorders, require to take such scan tests regularly to keep a track of their bone health.
DEXA Scan is quick, painless and the preferred method to measure BMD. It takes
5 minutes and is completely non-invasive.
What do the results mean ?
Your DEXA results will be read by a radiologist and given to you and your doctor in a few days.
The scoring system for the scan measures your bone loss against that of a healthy young adult, according to standards established by the WHO. This is called your T score. It’s the standard deviation between your measured bone loss and the average.
• A score of -1 or above is considered normal.
• A score between -1.1 and -2.4 is considered as osteopenia, increased risk for fracture.
• A score of -2.5 and below is considered as osteoporosis, high risk for fracture.
Your results may also give you a Z score, which compares your bone loss to that of others in your age group.
The T score is a measure of relative risk, not a prediction that you’ll have a fracture.
Your doctor will go over the tests results with you. They’ll discuss whether treatment is necessary, and what your treatment options are. The doctor may want to follow up with a second DEXA scan in three years, to measure any changes.
