A DEXA scan, or dual-energy X-ray absorptiometry, is a type of bone density test used to measure bone mineral density. It is the most accurate and reliable way to diagnose and monitor osteoporosis and osteopenia.
What is a Bone Density Test?
A bone density test is a type of imaging test that measures the amount of minerals in your bones. It is used to diagnose and monitor osteoporosis and osteopenia, which are conditions that cause bones to become weak and brittle.
What is a DEXA Scan?
A DEXA scan is a type of bone density test that uses a low-dose X-ray to measure the amount of minerals in your bones. It is the most accurate and reliable way to diagnose and monitor osteoporosis and osteopenia.
What is Osteoporosis?
Osteoporosis is a condition that causes bones to become weak and brittle. It is most common in older adults, but can affect people of any age. It is caused by a decrease in bone mineral density, which can lead to an increased risk of fractures.
What is Osteopenia?
Osteopenia is a condition that causes bones to become weak and brittle. It is similar to osteoporosis, but is less severe. It is caused by a decrease in bone mineral density, which can lead to an increased risk of fractures.
How Does a DEXA Scan Work?
A DEXA scan uses a low-dose X-ray to measure the amount of minerals in your bones. The X-ray is passed through the body and the amount of minerals in the bones is measured. The results of the scan are used to diagnose and monitor osteoporosis and osteopenia.
Who Gets a DEXA Scan?
A DEXA scan is typically recommended for people who are at risk for osteoporosis or osteopenia. This includes people who are over the age of 65, postmenopausal women, and people who have a family history of osteoporosis.
What Else Do Healthcare Providers Use DEXA Scans For?
In addition to diagnosing and monitoring osteoporosis and osteopenia, healthcare providers may use DEXA scans to diagnose other conditions such as bone tumors, fractures, and arthritis.
How Often Should a DEXA Scan Be Done?
The frequency of DEXA scans depends on the individual and their risk factors for osteoporosis and osteopenia. Generally, it is recommended that people at risk for these conditions have a DEXA scan every two years.
How Should I Prepare for a DEXA Scan?
Before having a DEXA scan, it is important to talk to your healthcare provider about any medications or supplements you are taking. You should also avoid wearing jewelry or clothing with metal zippers or buttons.
How is a Bone Density Test Done?
A bone density test is done by lying on a table while a low-dose X-ray is passed through the body. The amount of minerals in the bones is then measured and the results are used to diagnose and monitor osteoporosis and osteopenia.
How Long Does a DEXA Scan Take?
A DEXA scan typically takes about 10-15 minutes.
Is a DEXA Scan Painful?
No, a DEXA scan is not painful. The X-ray used is very low-dose and does not cause any discomfort.
How Accurate Are DEXA Scans?
DEXA scans are very accurate and reliable. They are the most accurate way to diagnose and monitor osteoporosis and osteopenia.
What Should I Expect After a DEXA Scan?
After a DEXA scan, you should expect to receive the results within a few days. Your healthcare provider will discuss the results with you and recommend any necessary treatments.
What Should I Ask My Healthcare Provider?
When talking to your healthcare provider about a DEXA scan, it is important to ask about the risks and benefits of the test, as well as any other questions you may have.
