Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD). An x-ray exam helps doctors diagnose and treat medical conditions.

Is bone density the same as bone densitometry?

What is a bone density test? A bone density test, DEXA, measures the mineral content of the bones in certain areas of the skeleton. It's a way to measure bone loss as you age. Healthcare providers sometimes call these tests bone densitometry tests, or DXA.

What is a bone densitometry test?

A bone density test is used to measure bone mineral content and density. It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine.
