Maintaining strong and healthy bones is vital for overall well-being, an active lifestyle, and quality of life. Our bones protect our organs, provide structure, and support mobility. Unfortunately, as we age, the risk of bone-related conditions such as osteoporosis increases, making bone density testing an essential diagnostic tool.
At Carolina Medical Associates, we offer bone density testing in Pineville, NC, as part of our health management and bone deterioration prevention strategy, to keep our patient’s bone health in tip-top shape. That’s why we have created this post to show you the significance of bone density testing, its purpose, procedure, risk, and how it can benefit your health.
What Is A Bone Density Test?
Contrary to popular belief, our bones are far from being static structures. Instead, they undergo a continuous renewal process, with specialized cells diligently breaking down old bone tissues and replacing them with new ones. Unfortunately, this delicate balance can shift as we age, resulting in accelerated bone loss.
When bone loss surpasses the rate of new bone formation, a condition known as osteoporosis can develop if left unchecked, making our bones brittle and porous. This is where a bone density test (also known as a bone mineral density (BMD) test) comes in handy.
This non-invasive diagnostic procedure measures the density and strength of your bones. It achieves that by measuring the amount of minerals, primarily calcium, present in a group or specific part of your bones to determine if there’s a decrease in bone mass. The test primarily focuses on the hip and spine, which are the most common sites for osteoporotic fractures. It provides information about your bone health, allowing your healthcare provider to determine your risk of experiencing fractures or developing conditions like osteoporosis and osteopenia and take actions to treat or prevent it.
When Is A Bone Density Test Required To Detect Osteoporosis?
Our family doctors in Pineville, NC, Dr. Avinash and Dr. Agha, typically recommend a bone density test to assess bone health and detect osteoporosis in the following groups of people or situations:
Postmenopausal Women: We generally advise women above the age of 65 to undergo a bone density test to assess their risk of osteoporosis. Women who have experienced early menopause around the age of 50 or have other risk factors, such as low body weight, may also be advised to go for a bone density test.
Men at Risk: While osteoporosis is more prevalent in women, men are also at risk. We may need to assess your bone health via bone density testing if you are 70 years old or above or have risk factors such as prolonged corticosteroid use, low testosterone levels, or chronic medical conditions.
Individuals with Fractures: If you have experienced a fracture resulting from minimal trauma, such as a minor fall, we may require a bone density test to assess your bone health and determine if osteoporosis is a contributing factor.
Medical Conditions and Medications: Certain medical conditions and medications can increase your risk of osteoporosis. We may suggest a bone density test if you’ve been taking medications such as corticosteroids for an extended period or have conditions such as diabetes, rheumatoid arthritis, hyperthyroidism, or chronic kidney disease.
Monitoring Treatment: If you’re already diagnosed with osteoporosis or undergoing treatment, a bone density scan may be necessary to monitor your treatment’s effectiveness or determine if adjustments are required.
Family History: If you have a family history of osteoporosis or fragility fractures or have experienced a fracture resulting from minimal trauma, such as a minor fall, we may recommend a bone density test to assess your risk or determine if osteoporosis is a contributing factor.
Lifestyle Factors: Certain lifestyle factors can increase your risk of developing osteoporosis. If you consume inadequate amounts of calcium and vitamin D, have a sedentary lifestyle, smoke, or consume excessive alcohol, a bone density test may be beneficial to evaluate your bone health.
Types of Bone Density Tests
Several types of bone density tests can help assess the strength and density of your bones. The two most commonly used methods are:
- Dual-Energy X-ray Absorptiometry (DEXA): DEXA is the most widely used and accurate technique for measuring bone density. It involves a low-dose X-ray that passes through the bones, measuring the amount of X-ray radiation absorbed by the bones. DEXA bone density scanning techniques typically focus on the hip and spine; the results are reported as T-scores.
- Quantitative Computed Tomography (QCT): QCT uses a specialized CT scanner to measure bone density. It provides three-dimensional images and can assess bone density in various body parts, such as the spine and hip. QCT is particularly useful for people who are obese or have conditions that affect the accuracy of DEXA scans, such as degenerative joint disease.
Other less commonly used methods include quantitative ultrasound (QUS) and peripheral dual-energy X-ray absorptiometry (pDEXA). These tests measure bone density at peripheral sites such as the heel, wrist, or finger. While not as accurate as DEXA or QCT, they can be useful when central DEXA is not readily available.
What To Expect During A Bone Density Testing in Our Pineville Office
Bone density testing conducted in our Pineville office is painless and quick, typically lasting around 10 to 30 minutes, depending on the areas being examined. Before the test, our primary care doctors will examine your medical history and ask you to avoid wearing jewelry, tight clothing with metal accessories, and medication such as calcium or vitamin D supplements that may interfere with the test result for at least 24 hours.
The bone density test is typically performed using a DEXA machine. You will be asked to lie on a padded table, and the technician will position you carefully, aligning your body according to the scanning area. During the test, the machine’s scanning arm emits a small amount of X-ray radiation that passes through the targeted area of your body, generating detailed images that your healthcare provider can use to determine your bone density.
What Do The Results Mean?
After the bone density test, your healthcare provider will analyze the results. The test results are typically reported as T-scores and Z-scores. T-scores compare your bone density to that of a healthy young adult of the same gender, while Z-scores compare your bone density to that of individuals of the same age and gender as you.
T-scores:
- Normal: T-score above -1
- Osteopenia (low bone density): T-score between -1 and -2.5
- Osteoporosis: T-score below -2.5
Z-scores:
- Z-score within the expected range for your age and gender is considered normal.
- A significantly low or high Z-score may indicate underlying medical conditions.
Our primary care physicians will interpret the results and discuss them with you. If necessary, they will recommend appropriate measures to manage your bone health, such as lifestyle changes, calcium and vitamin D supplementation, medications, and regular follow-up tests.
Are There Any Risks Involved?
Bone density testing is generally safe and non-invasive. However, it involves the use of X-rays, which increases your radiation exposure. Although the radiation dose is relatively low compared to other imaging techniques, repeated or cumulative exposure to radiation over time may pose a slight risk of developing cancer, especially for individuals who undergo frequent testing. However, the benefits of bone density testing often outweigh the potential risks from radiation exposure, particularly for individuals at high risk of osteoporosis.
How Frequently Do I Need Bone Testing To Detect Osteoporosis?
The ideal frequency of bone density testing varies, depending on your age, sex, previous test results, and whether you’re undergoing treatment for osteoporosis. The guidelines below can help you determine how often you should undergo testing to detect osteoporosis:
| Bone density result | T-score | Years to next text |
| Borderline osteoporosis | Between -2.0 and -2.5 | 1 year |
| Moderately low | Between -1.5 and -2.0 | 5 years |
| Mildly low | Between -1.0 and -1.5 | 15 years |
| Normal (even for a young woman) | -1.0 or higher | 15 years |
