How Do You Read a Bone Density Scan

Bone Density Test

A bone density test is the only examination that can diagnose osteoporosis before a cleaved bone occurs. This exam helps to estimate the density of your bones and your chance of breaking a os. BHOF recommends a bone density test of the hip and spine by a central DXA machine to diagnose osteoporosis. DXA stands for dual energy x-ray absorptiometry.

You can find out whether y'all take osteoporosis or if you should be concerned about your bones by getting a bone density test. Some people likewise call it a bone mass measurement examination. This exam uses a machine to measure your os density. It estimates the amount of bone in your hip, spine and sometimes other bones. Your test issue will aid your healthcare provider make recommendations to assistance you protect your basic.

Are you a postmenopausal woman or man historic period l and older? Have yous recently cleaved a bone? If you answered "yes" to both questions, you should talk to your doctor or other healthcare provider about getting a bone density exam if you've never had i.

What a Bone Density Exam Can Do

A bone density test tells you lot if you accept normal bone density, low bone density (osteopenia) or osteoporosis. It is the only test that tin can diagnose osteoporosis. The lower your bone density, the greater your adventure of breaking a bone. A bone density exam can help yous and your healthcare provider:

• learn if you take weak bones or osteoporosis before you break a bone
• predict your chance of breaking a os in the future
• see if your bone density is improving, getting worse or staying the aforementioned
• find out how well an osteoporosis medicine is working
• permit yous know if you take osteoporosis after you lot break a os

Who Should Accept a Bone Density Exam?

BHOF recommends that you lot have a bone density test if:

• you are a woman age 65 or older
• y'all are a man historic period 70 or older
• you break a bone afterwards age 50
• you are a adult female of menopausal historic period with risk factors
• yous are a postmenopausal woman nether age 65 with risk factors
• you are a man age fifty-69 with run a risk factors

A os density test may also be necessary if you lot have any of the following:

• an X-ray of your spine showing a break or bone loss in your spine
• back pain with a possible suspension in your spine
• height loss of ½ inch or more within one year
• full acme loss of 1½ inches from your original pinnacle

Types of Os Density Tests

DEXA is a non-invasive test to measure bone density.

Central DXA

BHOF recommends a bone density exam of the hip and spine using a central DXA machine to diagnose osteoporosis. DXA stands for dual energy ten-ray absorptiometry. When testing can't be washed on the hip and spine, BHOF suggests a central DXA exam of the radius bone in the forearm. In some cases, the type of bone density testing equipment used depends on what is bachelor in your community.

Healthcare providers measure bone density in the hip and spine for several reasons. Offset, people with osteoporosis take a greater chance of fracturing these bones. Second, broken bones in the hip and spine can cause more serious problems, including longer recovery time, greater pain and fifty-fifty disability. Os density in the hip and spine can also predict the likelihood of future breaks in other bones.

With almost types of bone density tests, a person remains fully dressed, but you lot do need to make certain no buttons or zippers are in the way of the area to be scanned. The exam commonly takes less than 15 minutes. Bone density tests are not-invasive and painless. This means that no needles or instruments are placed through the peel or torso. A central DXA uses very little radiations. You lot are actually exposed to 10–15 times more than radiation when you fly roundtrip between New York and San Francisco.

When repeating a bone density test, information technology is best to employ the same testing equipment and have the examination done at the same place each time. This provides a more accurate comparing with your last test consequence. Although it is not always possible to have your bone density test at the aforementioned place, information technology is nevertheless important to compare your current bone density scores to your previous scores.

Standard x-rays cannot be used in place of bone density tests. Unlike bone density tests, 10-rays are not able to evidence osteoporosis until the disease is well advanced. However, X-rays tin can be used in add-on to a DXA to find broken basic in the spine or elsewhere.

Screening Tests

Also called peripheral tests, screening tests measure out bone density in the lower arm, wrist, finger or heel. The types of peripheral tests are:

• pDXA (peripheral dual free energy x-ray absorptiometry)
• QUS (quantitative ultrasound)
• pQCT (peripheral quantitative computed tomography)

Screening tests can aid place people who are most likely to benefit from farther bone density testing. They are also useful when a central DXA is not available. These tests are often washed at health fairs and in some medical offices. Screening tests cannot accurately diagnose osteoporosis and they should not exist used to see how well an osteoporosis medicine is working.

If you take a peripheral bone density test, yous should follow upwards with your healthcare provider. Hash out whether y'all need additional testing, such as a central DXA test of the hip and/or spine. The results of a peripheral exam cannot be compared with the results of a central DXA.

People of Larger Size. Most key DXA machines cannot mensurate bone density in the hip and spine of patients who weigh more than than 300 pounds. Some newer machines tin measure out bone density in people who weigh up to 400 pounds, but these machines are not widely bachelor. When the hip and spine cannot be measured, some healthcare providers recommend a central DXA test of the radius bone in the forearm and a peripheral bone density test of the heel or another bone. Doing both of these tests might provide more consummate information.

Where to Accept a Bone Density Test

Most people need a prescription or referral from their healthcare provider to have a bone density exam. If y'all're not sure where to go for a bone density test, contact your healthcare provider or your insurance plan to find out where the test is bachelor. Besides, virtually hospital radiology departments, private radiology groups and some medical practices offer os density testing.

When you go for your engagement, be certain to have the prescription or referral with you. The testing centre will send your bone density test results to your healthcare provider. You may want to make an appointment to hash out your results with your healthcare provider.

How Oftentimes to Echo a Bone Density Test

People taking an osteoporosis medicine should repeat their bone density test by central DXA every one – two years. After starting a new osteoporosis medicine, many healthcare providers will repeat a bone density test after one year.

Understanding Bone Density Exam Results

Your bone density examination results are reported using T-scores. A T-score shows how much your bone density is higher or lower than the bone density of a healthy 30-twelvemonth one-time adult. A healthcare provider looks at the lowest T-score to diagnosis osteoporosis.

What Your T-score Means. According to the Earth Wellness Organization (WHO):

• A T-score of -one.0 or to a higher place is normal bone density. Examples are 0.9, 0 and -0.9.
• A T-score between -1.0 and -2.5 ways you have low bone density or osteopenia. Examples are T-scores of -1.one, -1.6 and -2.4.
• A T-score of -2.5 or beneath is a diagnosis of osteoporosis. Examples are T-scores of -2.6, -iii.3 and -3.9.
• The lower a person's T-score, the lower the bone density. A T-score of -1.0 is lower than a T-score of 0.5 and a T-score of -3.five is lower than a T-score of -three.0.

Guide to Understanding T-scores
Category	T-scores
	Range	Examples
Normal Os Density	-ane and above	+0.5
		0
		-one.0
Low Os Density (Osteopenia)	Between -1 and -2.5	-1.1
		-ane.five
		-2.four
Osteoporosis	-2.v and below	-ii.5
		-3.0
		-four.0

Your os density test result too includes a Z-score that compares your bone density to what is normal in someone your age and body size. Among older adults low bone mineral density is mutual, so Z-scores can be misleading.

Well-nigh experts recommend using Z-scores rather than T-scores for children, teens, women still having periods and younger men. BHOF does not recommend routine bone density testing in these age groups. A Z-score above -2.0 is normal according to the International Society for Clinical Densitometry (ISCD). A diagnosis of osteoporosis in younger men, premenopausal women and children should not be based on a bone density test consequence alone.

When to Consider Handling

The results of a bone density exam aid your healthcare provider make recommendations virtually what you can do to reduce your take chances of breaking a os. When making a decision about handling with an osteoporosis medicine, your healthcare provider will likewise consider your risk factors for osteoporosis, your likelihood of breaking a bone in the future, your medical history and your current health.

Beneath are handling guidelines for postmenopausal women and men age 50 or older:

• Most people with T-scores of -1.0 and above (normal bone density) do non need to have an osteoporosis medicine.
• Some people with T-scores between -ane.0 and -2.5 (low bone density or osteopenia) should consider taking an osteoporosis medicine when they accept certain gamble factors.
• All people with T-scores of -2.v and below (osteoporosis) should consider taking an osteoporosis medicine.

What About Depression Bone Density?

Having low bone density or osteopenia does not mean y'all will get osteoporosis. It ways y'all accept a greater chance of developing osteoporosis if you lose bone in the future. While nosotros've known that people with osteoporosis should consider treatment to reduce the run a risk of broken bones, it hasn't always been clear when to care for people who take low bone density.

The online fracture hazard assessment tool called FRAX® can help healthcare providers with these decisions. FRAX is a tool that calculates a person's absolute fracture risk or an estimate of the chance of breaking a bone in the next ten years. FRAX can assist to identify people who accept a greater chance of breaking a bone as well as people who might benefit from taking an osteoporosis medicine.
