Approximately 36 million Indians are currently suffering from Osteoporosis, which makes the disease a very prevalent one amongst the Indian population. Osteoporosis is a condition wherein gradual loss of calcium causes the bones to thin, become weak and fragile, leaving them prone to breakage. Postmenopausal women fall in the top high-risk category of suffering from osteoporosis.

Regular scans, preventive tests and early detection is the key to keeping the onset of the condition in check and taking measures to keep it from aggravating.

What is a DEXA scan used for?

A Dual-Energy X-ray Absorptiometry (DEXA) scan is an improved form of x-ray technology that helps in the accurate detection of Osteoporosis in the body. DEXA bone densitometry is an established standard to measure the bone mineral density (BMD) in the body. It is generally performed on the hips and the lower spine, but can also be used to screen the wrist, heel and fingers.

A DEXA scan is strongly recommended if you :

  • Are postmenopausal and are not taking oestrogen pills
  • Are postmenopausal and are regularly consuming oestrogen pills, but are taller than 5'7" or weigh less than 55 kg
  • Possess a personal or family history of type 1 diabetes, osteoporosis, liver disease, thyroid or kidney disease
  • Have ever experienced  a fracture after suffering from a mild trauma
  • Have clinical conditions associated with bone loss
  • Possess high bone turnover, reflected in the form of excessive collagen in urine samples
  • Are on medications that cause bone loss, such as corticosteroids, anti-seizure medication, barbiturates or high-dose thyroid replacement drugs

How is a DEXA scan conducted?

A DEXA scan is performed in the following way:

  • After putting on a hospital gown, you are asked to lie down on a padded table that has an X-ray generator below the table, connected to an imaging device or detector.
  • Depending upon the area being examined, the detector is slowly passed over the body, generating images on a computer.


The procedure time is 10-20 minutes.


How can I prepare for a DEXA scan?

  • Avoid taking calcium supplements for at least 24 hours before your bone density test
  • Wear loose, comfortable clothing without zippers, metal buttons and belts during the examination.
  • If you have had a barium examination or have been injected with a contrast material for a CT or radioisotope scan, you may be asked to wait for 10-14 days.


At Apollo Clinic, we possess cutting-edge central as well as peripheral DEXA equipment in order to correctly measure BMD. We follow rigorous procedures and constitute of the most competent and experienced team of technologists, radiographers, doctors and nurses ensure that each DEXA result is precise and accurate.
