Does a bone density test show rheumatoid 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.

What is the difference between osteoporosis and rheumatoid arthritis?

As the cartilage breaks down, bone begins to rub against bone. This causes severe pain, stiffness, and other symptoms brought about by osteoporosis. Rheumatoid arthritis, on the other hand, is an autoimmune disorder. This condition is caused by a specific disease rather than the passage of time.

Can a bone scan detect rheumatoid arthritis?

Bone scintigraphy (BS) that utilizes Tc-99m phosphonate compounds has high sensitivity but low specificity for the detection of bone and joint disease. In other words, using this test, we can easily identify active arthritis in patients, although the results are not specific for RA.

Will DEXA scan show arthritis?

When bone density is measured using DXA scanning, people with advanced (but not early) osteoarthritis in the spine (but not the hip) can appear to have a higher bone density than that measured by other methods because osteophytes (bone spurs) and disc narrowing may give the impression that the bone is thicker than it …

At what age should you stop getting bone density tests?

Women should get a bone scan at age 65. Men age 70 and up may want to talk with their doctors about the risks and benefits before deciding. Younger women, and men ages 50 to 69, should consider the test if they have risk factors for serious bone loss.

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.

Which type of arthritis is the most crippling?

Rheumatoid arthritis (RA) is recognized as the most disabling type of arthritis.

Which is worse osteo or rheumatoid arthritis?

OA is more common than RA. Both involve inflammation in the joints, but RA causes much more inflammation. Until recently, experts believed that inflammation was not a feature of OA, and researchers are still investigating the role that it plays in the illness — whether it is a cause or a result of the condition.

What blood test shows if you have rheumatoid arthritis?

Blood tests

People with rheumatoid arthritis often have an elevated erythrocyte sedimentation rate (ESR, also known as sed rate) or C-reactive protein (CRP) level, which may indicate the presence of an inflammatory process in the body.

Why would a rheumatologist order a bone scan?

The primary indications for scanning were to confirm a clinical diagnosis (38%), to exclude a diagnosis (34%), and to localize the site of pain (17%). The common diseases that rheumatologists were attempting to confirm or exclude with bone scanning were inflammatory arthritis, malignancy, and fracture.

What does rheumatoid arthritis look like on bone scan?

Other radiographic features of rheumatoid arthritis include loss of bone mineralization (osteopenia) in the bones bordering the joints; bony erosions, and large cysts around the joint. Subluxations and joint malalignment also occur.

Can you wear a bra for a DEXA scan?

Patients should not have had a barium study, radioisotope injection, or an oral or IV contrast material from a CT scan or MRI within 7 days prior to their DEXA exam. Patient should wear loose, comfortable clothing. Sweat suits and casual attire without zippers, buttons, grommets, metal hooks, or underwire bra.

What happens if you take calcium before a DEXA scan?

Why can’t I take calcium supplements or multiple vitamins on the day of my DEXA scan prior to my test? If the calcium supplement is not completely dissolved, it will be interpreted by the DEXA instrument as extra bone and may produce an inaccurate reading.
