Bone Density Scan – Austra Health

A bone density scan is a medical test that measures the density of your bones. It is a type of scanning procedure that uses low levels of radiation to assess the strength of your bones. This test is particularly important for women, as they are more prone to develop osteoporosis, a condition characterized by weak and brittle bones.

The bone density scan, also known as a dual-energy X-ray absorptiometry (DEXA) scan, is the most common and accurate way to diagnose osteoporosis. During the test, a small amount of radiation is used to scan your hips, spine, or legs, depending on which area of your body needs to be assessed. The scan provides a measurement called a T-score, which compares your bone density to that of a normal healthy young adult.

Women who have reached menopause, have a family history of osteoporosis, or have certain risk factors for the disease should consider getting a bone density scan. This test can help identify if there is a need for further treatment or preventive measures, such as increased calcium intake or medications, to maintain bone health. It is important to note that the radiation exposure from a bone density scan is minimal and the benefits of early detection far outweigh the risks.

What is it used for

A bone density scan, also called a DEXA scan, is a medical test used to diagnose osteoporosis and assess a person’s risk of bone fractures. It is primarily used for individuals who are at high risk of developing osteoporosis.

Osteoporosis is a condition in which the bones become weak and brittle, increasing the risk of fractures. This condition is more common in women, especially after menopause, but it can also affect men.

During a bone density scan, a machine will measure the amount of calcium and other minerals in your bones, focusing mainly on your hips and spine. The results of the scan will provide your health provider with information about the density of your bones and whether they are within the normal range.

If your bones are found to have a lower density, you may be diagnosed with osteoporosis or osteopenia, a condition where bone density is lower than normal but not yet considered osteoporosis.

The bone density scan is recommended for people who have certain risk factors for osteoporosis or have experienced fractures due to weak bones. These risk factors can include age, family history, medical history, certain medications, lifestyle factors, and certain diseases or conditions.

In addition to diagnosing osteoporosis, a bone density scan can also be used to monitor the effects of treatment for the condition. Changes in bone density over time can indicate whether the treatment is effective in preventing further bone loss.

It is important to note that a bone density scan is not the only test used to assess bone health. Other tests, such as blood tests and urine tests, may also be performed to assess calcium levels and other factors related to bone health.

If you are at risk of developing osteoporosis or have experienced fractures, it is important to discuss with your healthcare provider whether a bone density scan is necessary for you. The scan can help identify potential problems with your bone health and allow for early intervention to prevent future fractures.

Why do I need a bone density scan

A bone density scan, also called a DEXA scan, is a test that uses low-dose radiation to measure the amount of calcium and other minerals in your bones. This scan is used to diagnose osteoporosis, a condition that causes weak and brittle bones.

If you are a woman over the age of 65, you should consider getting a bone density scan. Women are more prone to developing osteoporosis after menopause due to hormonal changes. However, men can also develop osteoporosis, especially as they age.

There are several other factors that may increase your risk of developing osteoporosis, such as a family history of the condition, being of Caucasian or Asian descent, having a small and thin frame, smoking, excessive alcohol consumption, and inadequate calcium intake.

A bone density scan is a painless and non-invasive procedure. During the scan, you will lie on a table while a machine scans your body, usually your spine and hips, but sometimes also your legs or wrist. The results of the scan will show how dense your bones are compared to a normal, healthy young adult.

If the scan shows that your bone density is lower than normal, it may indicate that you have osteoporosis or that you are at risk of developing the condition in the future. Your doctor will use the results of the scan, along with other tests and your overall health, to determine the best course of action for you.

It is important to remember that osteoporosis is a silent disease, meaning it often goes unnoticed until a fracture occurs. By getting a bone density scan, you can detect osteoporosis early and take steps to prevent fractures and maintain bone health.

What happens during a bone density scan

A bone density scan, also called a DXA scan, is a special type of scanning test that is commonly used to diagnose bone health in women. It is a painless and non-invasive procedure that measures the amount of calcium and other minerals in the bones.

Preparation

Before the scan, women should ensure that they are wearing loose, comfortable clothing without any metal zippers, buttons, or jewelry. They may also need to remove any metal objects, such as belts or bras, that could interfere with the scan.

The scanning process

During the scan, the woman will lie down on a table and a scanning device will be used to measure the density of her bones, usually in the hips and spine. The woman’s legs may be secured to prevent movement during the scan. The technician will position the scanner over the body part being examined and the scan will be completed within a few minutes.

Most bone density scans are done using a DXA machine, which is the most accurate and widely used method for measuring bone density. The results of the scan are compared to a normal range of bone density for a person’s age and sex to assess their bone health.

The scan results will show if a person has normal bone density, low bone density (osteopenia), or the most severe form of low bone density (osteoporosis). Women with low bone density are at an increased risk of fractures and may need additional tests or treatment to prevent further bone loss.

Overall, a bone density scan is a valuable tool in assessing a woman’s bone health, especially as she gets older. By identifying low bone density or osteoporosis early, women can take steps to prevent fractures and maintain their bone health.

Will I need to do anything to prepare for the test

Before getting a bone density scan, there are a few things you should keep in mind. Firstly, this test involves a small amount of radiation. However, the amount is minimal and is generally considered to be safe. The benefits of a bone density scan far outweigh any potential risks.

There is usually no need for any special preparation before the test. You can eat and drink normally, and take any medications as prescribed by your doctor.

However, it’s important to let your doctor know if you have had any recent tests that involved the use of contrast material, as this may interfere with the accuracy of the bone density scan results.

If you are pregnant or think you may be pregnant, you should inform your doctor before undergoing a bone density scan, as radiation exposure during pregnancy can pose a risk to the developing fetus.

During the scan, you will need to lie still on a table while a machine called a DEXA scanner takes images of your bones, usually focusing on the hip and spine. The scanning process is quick and painless, and you can resume your normal activities immediately afterwards.

It’s also worth noting that women should be mindful of their calcium intake, as low levels of calcium can contribute to bone loss. Your doctor may advise you to take calcium supplements or make dietary changes to support bone health.

In conclusion, there is generally no need for any special preparations before a bone density scan. The test is a simple procedure that can help diagnose bone conditions and assess the risk of fractures. With its minimal radiation exposure, it is considered safe and is commonly used to monitor bone health in women, especially those at higher risk. If you have any concerns or questions, it’s best to discuss them with your doctor.

Are there any risks to the test

Bone density scans, also called DXA scans, are generally safe and painless. The test uses a very small amount of radiation, equivalent to about one-tenth of a chest x-ray. The amount of radiation used is low, and the benefits of having the scan usually outweigh any potential risks.

There are no known risks associated with having a bone density scan. However, it’s important to let your healthcare provider know if you are pregnant or think you might be pregnant, as radiation exposure can be harmful to a developing baby. Additionally, if you have had any recent imaging tests that involved the use of contrast dye, such as a CT scan or MRI, you should inform your healthcare provider as well.

It’s also important to note that the scan itself doesn’t require any special preparation or precautions. However, if you are taking any medications or supplements that contain calcium, you should let your healthcare provider know, as these can affect the results of the test. Similarly, if you have any metal implants or devices in your body, such as a pacemaker or joint replacements, you should inform your healthcare provider.

What do the results mean

After undergoing a bone density scan, the results provide important information about the health of your bones. The scan, also called a dual energy X-ray absorptiometry (DEXA) scan, measures the density of your bones and compares it to that of a young adult of the same gender.

Normal results

If your bone density is within the normal range, it means that your bones have a healthy density and strength. This is a positive result and indicates that you have a lower risk of developing osteoporosis or fractures.

Abnormal results

If your bone density is below the normal range, it may indicate that you have low bone mass, a condition called osteopenia, or osteoporosis. Further tests or scans may be necessary to diagnose the exact condition of your bones and determine the appropriate treatment plan.

It is important to note that not all low bone density results mean you have osteoporosis. Other factors such as age, gender, family history, and overall health should be considered when interpreting the results.

If you are a postmenopausal woman or have other risk factors associated with osteoporosis, a low bone density result should be taken seriously. Your healthcare provider can help determine the best course of action, which may include lifestyle changes, medications, and additional testing.

Keep in mind that a bone density scan only measures the density of your bones and does not provide information about your overall bone health. It does not measure bone quality or assess the risk of fractures. Other factors such as vitamin D levels, calcium intake, and physical activity also play a role in maintaining healthy bones.

If you have concerns about your bone health, it is recommended to discuss them with your healthcare provider, who can provide guidance and advice based on your individual situation and risk factors.

Is there anything else I need to know about a bone density scan

A bone density scan, also known as a dual-energy X-ray absorptiometry (DEXA) scan, is a test used to measure the mineral content and density of your bones. It is a safe and painless procedure that can help diagnose osteoporosis, a condition that causes weakened and brittle bones.

During the scan, you will lie on a padded table while a machine passes over your body, scanning specific areas, usually your hips and spine. The machine emits a small amount of radiation, similar to that of a standard X-ray, but the exposure is minimal and considered safe.

It is important to note that having a bone density scan does not necessarily mean you have osteoporosis. The results of the scan are usually compared to a database of people with normal bone density for your age and sex. If your bone density is significantly lower than normal, it may indicate a higher risk of fractures and the need for further evaluation or treatment.

There are factors that can affect your bone density, such as age, sex, and certain medical conditions. Women are more likely to have lower bone density, especially after menopause due to hormonal changes. Other risk factors include a family history of osteoporosis, smoking, excessive alcohol consumption, and a sedentary lifestyle.

It’s important to discuss your test results with your healthcare provider, as they can provide more information about your bone health and offer recommendations for maintaining or improving it. They may suggest lifestyle changes such as increasing your intake of calcium and vitamin D, engaging in weight-bearing exercises, and quitting smoking.

Remember, a bone density scan is just one tool used to assess bone health. It should be used in conjunction with other tests and clinical evaluation. If you have concerns about your bone health, it’s best to talk to your healthcare provider about your specific situation and whether a bone density scan is appropriate for you.
