How Does a DXA Scan Help Diagnose Osteoporosis?
Published: Sep 05, 2024
The DXA scan is a crucial tool in the diagnosis of osteoporosis, helping to measure bone density and assess fracture risk effectively.
The Basics of a DXA Scan
A DXA scan, or dual-energy x-ray absorptiometry, is a painless and non-invasive test that measures bone mineral density (BMD). It uses low-level x-rays to assess the strength of bones, particularly in the spine and hip, which are common areas affected by osteoporosis. This test is essential in diagnosing osteoporosis and monitoring bone health over time.
Interpreting DXA Scan Results
The results of a DXA scan are presented as T-scores and Z-scores. A T-score compares your bone density to that of a healthy young adult, with a score of -2.5 or lower indicating osteoporosis. A Z-score compares your results to others of your age, gender, and size, with low scores suggesting potential underlying conditions affecting bone health.
Why Get a DXA Scan?
A DXA scan is recommended for postmenopausal women, men over 50, and individuals with risk factors for bone loss. Early detection of low bone density can lead to timely interventions, helping to prevent fractures and manage osteoporosis effectively. It's a proactive step in maintaining long-term bone health.
