When is a bone density scan recommended for osteoporosis?

The scan uses low-dose imaging to measure mineral density at areas such as the hip and lower spine. Results help a clinician judge whether bone density is within an expected range, reduced, or low enough to support an osteoporosis diagnosis. Testing may be considered after a fragility fracture, when medical conditions or medicines can weaken bone, or when age and other risk factors make screening appropriate.

A scan does not explain every cause of bone loss and does not predict exactly whether or when a fracture will happen. Your clinician may combine the result with your history, examination, and other tests.

Tell the imaging team if you could be pregnant, recently had an examination using contrast material, or take medicines and supplements that may affect the appointment. Wear comfortable clothing and follow the centre's instructions. The scan is usually brief and does not require an injection. Keep the report so future results can be compared at the same facility when possible.

Discuss the result with the clinician who requested it. Depending on the findings, the plan may include weight-bearing activity, fall prevention, nutrition advice, repeat testing, or medicine for fracture prevention.

Arrange medical review after a fall or minor injury that causes new bone pain, loss of function, or suspected fracture. Seek urgent care for severe pain, an obvious deformity, inability to bear weight, numbness, or a limb that looks pale or cold. A scan is not an emergency test for sudden injury; urgent assessment comes first.

Ask what prompted the scan, which body areas will be measured, whether any medicines affect preparation, and when you should receive the result. You can also ask whether you need blood tests, how often follow-up testing is useful, and what steps protect your bones now.
