A DEXA scan is a medical examination that measures bone density. It essentially assesses the likelihood of developing osteoporosis using a low dosage of X-rays. Doctors or individuals can utilize this tool to evaluate bone health and determine if therapy is necessary. But, it can be challenging to understand the findings of a DEXA scan. And many are unable to properly evaluate the indications given by the figures. This article will walk you through the steps of how to read a DEXA scan, explaining the various values and what they indicate and how to interpret the results.
What is a DEXA Scan?
A DEXA scan is a diagnostic procedure that assesses lean muscle mass, body fat, and bone mineral density. The technique takes a few minutes to complete and is rapid, painless, and non-invasive. The patient is placed on a table to undergo the examination while a machine transmits a low-dose X-ray across the body. The equipment calculates the radiation absorbed to determine the bone mineral density after the bones and soft tissues absorb the X-rays.
For the accurate diagnosis of osteoporosis, a disorder that makes bones brittle and fragile, a DEXA scan is a crucial tool. Millions of individuals worldwide suffer from osteoporosis, which affects women more frequently than males. Healthcare professionals use DEXA scans to assess bone health in older adults and postmenopausal women who have a higher risk of developing osteoporosis.
Components of A DEXA Scan Report
A DEXA scan report contains several values that can be difficult to understand. Click here to check the reliability of the DEXA scan. Here is a primer on how to read a DEXA scan report.
T-Score
The T-score, which is used to diagnose osteoporosis, is the most important statistic in a DEXA scan report. The T-score uses a standard deviation to compare the patient’s bone density to that of a young adult of the same gender. The bone density deemed normal has a T-score of -1.0 or above. Low bone density, which is an indication of osteopenia, is indicated by a T-score between -1.0 and -2.5. When the T-score is -2.5 or lower, osteoporosis is present.
Z-Score
Another statistic found in a DEXA scan report that contrasts the patient’s bone density with that of someone of a similar age, gender, and ethnicity is the Z-score. The Z-score is used to pinpoint additional illnesses, such as hormonal imbalances or drug interactions, that could harm bone health.
Bone Mineral Density
Bone mineral density (BMD), measured in grams per square centimeter (g/cm2), is a measurement of the amount of calcium and other minerals in bones. It is utilized to ascertain the probability of fractures. While a lower BMD suggests weaker bones, a higher BMD indicates stronger bones.
Body Fat and Lean Muscle Mass
A DEXA scan can measure both your lean muscle mass and body fat, allowing healthcare professionals to assess your overall health and determine your risk of developing obesity-related disorders
Interpreting the Results

T-Score
Your bone density is regarded as normal if your T-score is -1.0 or above and you have a low risk of fractures. Maintaining a healthy lifestyle and strong bones, though, is still imperative.
You have osteopenia if your T-score is between -1.0 and -2.5, which is a result of low bone density. You now have an increased risk of getting osteoporosis. Your doctor might advise making lifestyle adjustments if you have osteopenia, such as boosting your calcium and vitamin D intake, exercising frequently, quitting smoking, and abstaining from excessive alcohol use. Additionally, your doctor can suggest drugs to help stop bone loss and lower the risk of fractures.
You have osteoporosis if your T-score is -2.5 or below, which suggests that your bones are fragile and brittle and that you are at a high risk of fractures. Your physician will suggest a course of action to assist in stopping further bone loss and lowering the risk of fractures. Medications like bisphosphonates or denosumab, calcium and vitamin D supplements, and lifestyle modifications are all possible forms of treatment.
Z-Score
Your bone density is suitable for your age, gender, and ethnicity if your Z-score falls within the usual range. If your Z-score is significantly lower than the expected range, your doctor may recommend further testing to identify any underlying medical conditions that could be affecting your bone health.
Bone Mineral Density
Your BMD is a gauge of the strength and density of your bones. While a lower BMD suggests weaker bones, a higher BMD indicates stronger bones. Healthcare professionals assess the severity of osteoporosis and the risk of fractures by using the BMD.. Your doctor could suggest lifestyle modifications and drugs if your BMD is low to assist in stopping additional bone loss.
Checking this specific statistic regularly is crucial for people as they age. The lowering of the BMD results in stress fractures and other bone-related injuries in older adults.
Body Fat and Lean Muscle Mass
A DEXA scan can determine both your body fat and lean muscle mass. Low muscle mass and high body fat are risk factors for osteoporosis, diabetes, and heart disease, among other illnesses. To enhance your body composition and general health, your doctor may advise adjusting your lifestyle, such as exercising and eating well.

Additional Insights
Knowing how to read a DEXA scan can reveal details about the body’s distribution of fat in addition to the results mentioned above, which can assist in determining the risk of developing specific diseases. For instance, extra belly fat has been connected to a higher risk of heart disease, diabetes, and several cancers. A DEXA scan can offer important insights into a patient’s overall health and risk of chronic diseases by examining the body’s fat distribution.
It’s crucial to remember that a DEXA scan is not the only viable methodology to gauge bone health. Blood tests to check for calcium, vitamin D, and other hormones that impact bone health may also be advised by your doctor. Your doctor may suggest additional imaging exams, including X-rays or CT scans, to assess bone health and spot fractures.
Improving and Checking Bone Health
If you are concerned about the health of your bones, inquire with your doctor to determine if a DEXA scan is appropriate for you. Your doctor can explain the test’s advantages and disadvantages and suggest the best course of action for your requirements.
There are various actions you may take to promote healthy bones and lower your risk of osteoporosis and fractures, in addition to routine bone density testing. These consist of the following:
Consume adequate amounts of vitamin D and calcium. Calcium is necessary for developing strong bones, and vitamin D facilitates calcium absorption in the body. Dairy products, leafy green vegetables, and fortified meals like orange juice and cereal can all provide the daily intake value of calcium. Sunlight, vitamin D pills, and some foods, including fatty fish and fortified foods, are all sources of vitamin D.
Do regular exercise. Weight-bearing activities like jogging, weightlifting, and walking can help increase and maintain bone density. On most days of the week, try to get in at least 30 minutes of moderate activity.
Steer clear of smoking and excessive alcohol use. Smoking and binge drinking can both weaken bones and raise the risk of fractures. If you smoke, discuss quitting methods with your doctor. If you do consume alcohol, do so sparingly.
Use prescription drugs as directed. If you have been diagnosed with osteoporosis or are at a high risk of fractures, your doctor may prescribe medication to prevent further bone loss and reduce the risk of fractures. It’s crucial to take these drugs exactly as directed and abide by your doctor’s recommendations for treating and monitoring your bone health.
Conclusion
Determining the risk of osteoporosis and evaluating bone health requires using a DEXA scan. Doctors and specialists use crucial measurements such as T-score, Z-score, BMD, body fat, and lean muscle mass to identify and track osteoporosis and other illnesses affecting bone health. You can work with your doctor to create a treatment plan that will support maintaining the health of your bones and preventing fractures by comprehending the values and analyzing the results.
