Understanding Bone Health and DEXA Scans
As you get older, maintaining your strength and mobility becomes a top priority. A key part of this is ensuring your bones remain strong and healthy. Your healthcare provider might mention a 'DEXA scan' as a way to check on your bone health, but what exactly is it? This simple, painless test is one of the most important tools for understanding your risk of bone-related issues and keeping you active for years to come.
At Pittsburgh Imaging & Wellness, we believe in empowering patients with clear information. Let's explore what a DEXA scan is, why it's important, and what you can expect.
What Is a DEXA (Dual-Energy X-ray Absorptiometry) Scan?
A DEXA scan is a non-invasive imaging test that measures bone mineral density (BMD). Think of it as a specialized, low-dose X-ray that provides detailed information about how strong and dense your bones are. The term 'dual-energy' refers to the two different X-ray beams used during the scan, which allows for a highly accurate reading of bone density, typically in the hip and spine.
It is considered the gold standard for diagnosing osteopenia (low bone mass) and osteoporosis, a condition that causes bones to become weak and brittle.
How Is a DEXA Scan Performed?
Getting a DEXA scan is a straightforward and comfortable process. You'll be asked to lie on a padded table while a mechanical arm passes slowly over your body. You can remain fully clothed, as long as you remove any metal objects like zippers or buttons.
The entire procedure is quick, usually lasting only 10 to 20 minutes. There are no injections or special preparations required. The amount of radiation used is extremely low—even less than what you would be exposed to on a cross-country flight.
Who Needs a DEXA Scan?
Your doctor will recommend a DEXA scan based on your specific risk factors. It is not a routine scan for everyone, but it is a crucial diagnostic tool for certain populations.
Common Reasons for Ordering a DEXA Scan
- Age: Women are typically advised to get their first DEXA scan around age 65, and men around age 70.
- Postmenopause: Estrogen levels drop significantly after menopause, which can lead to rapid bone loss. Your provider may recommend a scan sooner if you are postmenopausal with other risk factors.
- History of Fractures: If you have broken a bone easily after the age of 50, it could be a sign of underlying bone weakness.
- Certain Medical Conditions: Conditions like rheumatoid arthritis, lupus, kidney or liver disease, and thyroid problems can affect bone health.
- Long-Term Medication Use: Extended use of certain medications, such as steroids (e.g., prednisone), can contribute to bone loss.
- Significant Height Loss: Losing an inch or more in height can be an indicator of compression fractures in the spine due to osteoporosis.
- Family History: A parental history of hip fractures increases your own risk.
Why Bone Health Matters, Especially with Aging
Strong bones provide the framework for your body, protect your vital organs, and allow you to move freely. As we age, our bodies naturally start to lose bone mass. If this loss happens too quickly, it can lead to osteoporosis.
The primary danger of osteoporosis is not the condition itself, but the high risk of fractures. A fracture of the hip, spine, or wrist can lead to:
- Chronic pain
- Loss of independence
- Reduced mobility
- A lengthy and difficult recovery
By monitoring your bone density, you and your doctor can take proactive steps to prevent fractures before they happen, helping you maintain an active and independent lifestyle.
How DEXA Scan Results Guide Your Care
After your scan, a radiologist will analyze the results and send a report to your doctor. The findings are given as a 'T-score,' which compares your bone density to that of a healthy young adult.
| T-Score | Diagnosis | What It Means |
|---|---|---|
| -1.0 and above | Normal Bone Density | Your bone density is considered normal. |
| Between -1.0 and -2.5 | Osteopenia (Low Bone Mass) | Your bone density is lower than normal, and you are at an increased risk of developing osteoporosis. |
| -2.5 and below | Osteoporosis | Your bone density is significantly low, and you have a high risk of fractures. |
Based on your T-score and other risk factors, your doctor will create a personalized treatment plan. This may include:
- Lifestyle changes: Increasing calcium and vitamin D intake, performing weight-bearing exercises like walking or lifting weights, and quitting smoking.
- Medications: Prescribing drugs designed to slow bone loss or build new bone.
- Follow-up scans: Scheduling future DEXA scans to monitor your bone density over time and see how well treatments are working.

Frequently Asked Questions
What is the difference between a bone scan and a DEXA scan?
A bone scan is a nuclear imaging test that detects abnormalities in bone metabolism, often used to find fractures, infections, or cancer in the bones. A DEXA scan, on the other hand, is a low-dose X-ray specifically designed to measure bone density and diagnose osteoporosis.
Do I need a doctor’s referral for a DEXA scan?
Yes, a DEXA scan is a medical imaging test that requires a referral from a healthcare provider. Your doctor will determine if the scan is appropriate for you based on your age, medical history, and risk factors.
Is a DEXA scan painful?
No, a DEXA scan is completely painless and non-invasive. You simply lie still on a comfortable, padded table for a few minutes while the scanner passes over you.
How often should I get a DEXA scan?
The frequency of DEXA scans depends on your initial results and risk factors. If your bone density is normal, you may not need another scan for several years. If you have osteopenia or osteoporosis, your doctor will likely recommend a follow-up scan every one to two years to monitor your condition and treatment effectiveness.
