Does rheumatoid arthritis show on a bone scan?

In RA patients, three-phase bone scintigraphy seems able to provide information on periarticular bony structure as well as inflammatory synovitis through perfusion or blood pool activity which is consistent with the central pathologic features of RA.

Will a bone scan show arthritis?

The test is very sensitive to any difference in bone metabolism. The ability to scan the entire skeleton makes a bone scan very helpful in diagnosing a wide range of bone disorders, including: Fractures. Arthritis.

How does arthritis show up on a bone scan?

Areas of extra bone activity (common in both cancer and arthritis) will show up on the scan because the radioactive substance collects in areas of new bone formation. These areas appear as dark patches on the film. Any part of the bone can be affected by cancer.

Can Rheumatoid arthritis cause bone lesions?

Although bone erosions occur in healthy people or patients with other joint diseases, they are more severe in patients with RA. Bone erosions arise early in the course of RA (within a few weeks to a few months of onset in some patients). They most often affect metacarpophalangeal joints and predict more severe disease.

What does rheumatoid arthritis look like on a bone scan?

Imaging can show bony erosions, small areas of bone loss caused by RA inflammation. Erosions are signs of severe RA, and they can lower joint function. Imaging may also detect bone changes like osteopenia, or weakening bones, or joint malalignment and stress fractures.

Does a bone scan show inflammation?

Bone scan is one of the most common and oldest examinations among all nuclear medicine procedures. It is used in the evaluation of benign bone disease like infection/inflammation and also is the standard of care for evaluating metastatic disease in the breast, prostate, and lung cancer.

What does a hot spot on a bone scan mean?

The areas where the radionuclide collects are called “hot spots,” and may indicate the presence of conditions such as arthritis , malignant (cancerous) bone tumors , metastatic bone cancer (cancer which has spread from another site, such as the lungs), bone infections , bone trauma not seen on ordinary X-rays, and …

What does rheumatoid arthritis do to the skeleton?

Inflammation, which is a major feature of rheumatoid arthritis contributes to joint pain and swelling, and cartilage damage, which then leads to erosion into the bone around the around the joint. Inflammation also affects bones, including contributing to the loss of bone mineralization.
