DEXA Bone Densitometry

A Dual-Energy X-ray Absorptiometry (DEXA) test is a bone density study used to determine whether or not you have osteoporosis or low bone mass, conditions that commonly affect women after menopause and, in some cases, men. DEXA at Imaging Healthcare Specialists in San Diego is a fast, safe and painless test that measures bone strength and can predict your risk for bone fracture. DEXA may also be used as a follow-up procedure to monitor response to specific medications.

Osteoporosis is a disease that is gaining increased attention as more people live longer, and with early detection, a number of treatments are available to maintain or improve bone density. All women over 65 and men over 65 with low testosterone levels should be screened for osteoporosis.

Frequently Asked Questions

Why is DEXA Bone Densitometry Important?

DEXA (Dual-Energy X-ray Absorptiometry) bone densitometry is important because it is the most accurate and widely used method for diagnosing osteoporosis, assessing fracture risk, and monitoring bone health over time. It helps detect bone loss early, allowing for timely intervention to prevent fractures and other complications.

How is DEXA Bone Densitometry Determined?

DEXA measures bone mineral density (BMD) by using low-dose X-rays to scan the hips and spine, which are the most common sites for osteoporosis-related fractures. The results are compared to a reference database and expressed as a T-score or Z-score to assess bone strength and fracture risk.

What Age Should I Get Scanned?

Women should consider getting a DEXA scan at age 65 and men at age 70. However, individuals with risk factors such as a family history of osteoporosis, previous fractures, certain medical conditions, or prolonged steroid use may need to get scanned earlier. Consult a medical professional who can advise you on what age to scan.

How Often Should I Get a DEXA Bone Densitometry Scan?

The frequency of DEXA scans depends on individual risk factors and initial results. Generally, if the first scan shows normal bone density or Osteopenia, a follow-up scan may be recommended every 2–5 years. If osteoporosis or significant bone loss is detected, more frequent monitoring may be necessary.

Who Should Prioritize Getting DEXA Bone Densitometry Scans?

Postmenopausal women and older men
Individuals with a history of fractures
Those with conditions affecting bone health (e.g., rheumatoid arthritis, chronic kidney disease)
People taking long-term corticosteroids or other medications that impact bone density
Those with a family history of osteoporosis

What are the Benefits of DEXA Bone Densitometry?

Early detection of osteoporosis and fracture risk
Non-invasive and painless procedure
Low radiation exposure
Helps guide treatment and lifestyle changes to maintain bone health

How Long Does the Scan Take?

A DEXA bone densitometry scan typically takes about 10 to 20 minutes, making it a quick and efficient test for assessing bone health.
