Osteoporosis, which weakens bones and increases the risk of fractures, affects many individuals, especially as they age. Understanding bone health and taking preventive measures can reduce the likelihood of complications. A DEXA scan is valuable in assessing bone density, offering clear insights into bone health,, and providing actionable data for better management.
What Is a DEXA Scan?
A DEXA scan, or dual-energy X-ray absorptiometry scan, is a diagnostic imaging test specifically designed to measure bone density. It is widely used to assess bone health in individuals who may be at risk for low bone density or developing conditions like osteoporosis. The scan is easy to perform, minimally invasive, and relatively quick. It uses a low dose of X-rays to evaluate the density of bones in specific areas, typically the hips, spine, and sometimes the forearm. The resulting data can help provide an accurate picture of overall bone strength.
How Does It Measure Bone Density?
A DEXA scan works by using two X-ray beams at different energy levels to assess bone density. Each beam passes through bone and soft tissue, distinguishing between the two types of material. The scan calculates bone density with high accuracy by analyzing how much of each beam is absorbed by the body.
This method is highly precise because it takes into account the impact of surrounding tissues, such as muscles and fat. These types of tissues could otherwise interfere with the measurement. Unlike older methods, such as single-photon absorptiometry, DEXA scans use a dual-energy approach that significantly reduces the likelihood of errors or inaccuracies for reliable results.
The data from these scans provides a clear numerical value that healthcare professionals use to assess bone health and identify risks, such as osteoporosis or fractures. As well as measuring bone density, these scans can also provide information about body composition. This can include the fat and lean mass volume, making them a valuable tools in medical and fitness settings. This comprehensive insight is particularly useful for tracking bone health over time or monitoring the effectiveness of treatments aimed at improving bone strength.
What Do Your Results Mean?
DEXA scan results include a T-score or Z-score, which compares your bone density to specific benchmarks. A T-score compares results to the bone density of a healthy young adult. A Z-score compares your results to individuals of the same age, sex, or body size.
Results help classify bone density levels as expected, low, or indicative of osteoporosis. Depending on the findings, professionals may recommend improving or maintaining bone health. These results are a baseline for monitoring changes over time through follow-up scans.
