Bone densitometry, also called dual-energy x-ray absorptiometry, DEXA or DXA, uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower (or lumbar) spine and hips) to measure bone loss.
DXA is a non-invasive test to measure bone density. A bone density test is a measurement of how much mineral, such as calcium, you have in your bones. The most common and most versatile test is with dual-energy X-ray absorptiometry (DXA).
DXA scan. The lumbar spine and proximal femur are imaged using two X-ray beams of different X-ray energy levels. Soft tissues of the body absorb the low energy beam, and bone absorbs the high energy beam.
23 Ιουν 2020 · There are a variety of bone density tests available, but the “gold standard” test for diagnosing osteoporosis is the DEXA scan (also written as “DXA scan“). The acronym stands for dual energy x-ray absorptiometry, and it measures bone density in the spine, hip, or wrist.
6 Αυγ 2024 · A DEXA scan is a dual-energy X-ray method that measures your bone mineral density and bone loss. It’s used to calculate osteoporosis and fracture risk.
