A DEXA scan is a type of medical imaging test. It uses very low levels of x-rays to measure how dense your bones are. DEXA stands for “dual-energy X-ray absorptiometry.” Medical experts consider DEXA scans to be the most useful, easy, and inexpensive test for helping to diagnose osteoporosis.
How long does a bone scan for osteoporosis take?
The scan usually takes 10 to 20 minutes. You’ll be able to go home after you have had it done.
How do you prepare for a bone density test?
Virtually no preparation is needed. Be sure to tell your doctor beforehand if you’ve recently had a barium exam or had contrast material injected for a CT scan or nuclear medicine test. Contrast materials might interfere with your bone density test.
What does a bone density scan involve?
A bone density scan, also known as a DEXA scan, is a type of low-dose x-ray test that measures calcium and other minerals in your bones. The measurement helps show the strength and thickness (known as bone density or mass) of your bones. Most people’s bones become thinner as they get older.
Why have I been sent for a bone density scan?
Bone density scans, also known as DEXA scans, help to work out your risk of breaking a bone. They’re often used to help diagnose bone-related health problems, such as osteoporosis, or to assess the risk of getting them.
What is the difference between a bone scan and a CT scan?
A CT scan is a high-resolution X-ray that gives detailed information about organ anatomy. A bone scan is a nuclear imaging test that aids in the diagnosis and tracking of several bone diseases. A CT scan uses a combination of X-rays and a computer to create images of the bones.
Can you wear a bra for bone density test?
Patient should wear loose, comfortable clothing. Sweat suits and casual attire without zippers, buttons, grommets, metal hooks, or underwire bra. Gowns are available, if necessary.
Do you have to undress for a bone density test?
In most cases, you do not need to undress. This scan is the best test to predict your risk for fractures, especially of the hip.
How long does it take to get results from a bone density test?
Although the timing varies according to the hospital, facility, and radiologist who will be assessing your DEXA scan, you probably will hear back from your doctor with the results within a week or two. The results of a bone density measurement (DEXA scan) are reported in two ways: as T-scores and as Z-scores.
What happens if your bone density is low?
A person may have low bone mass at any age but not develop osteoporosis. However, if a person has low bone mass and continues to lose bone density, this may lead to osteoporosis. A combination of low bone mass and a risk factor for fracture may increase your risk for broken bones, too.
Can a bone density test detect arthritis?
A bone density test isn’t typically used to diagnose arthritis. Instead, it’s most often used to diagnose early signs of bone loss or osteoporosis. But if you have inflammatory types of arthritis, like RA or PsA, you may be at risk for developing osteoporosis.
Does bone density affect weight?
The effect of weight and of weight change on bone mineral density was in general much less in men than in women. Our results suggest that the strong effect of weight on bone mineral density is due to load on weight-bearing bones in both sexes.
What does osteoporosis pain feel like?
Sudden, severe back pain that gets worse when you are standing or walking with some relief when you lie down. Trouble twisting or bending your body, and pain when you do. Loss of height.
