Which disorders result in Intense radiotracer uptake on a bone scan in multiple joints

Which disorders result in Intense radiotracer uptake on a bone scan in multiple joints?

Polyarticular radiotracer uptake on a bone scan is typically associated with arthritic conditions, such as osteoarthritis, rheumatoid arthritis, psoriatic arthritis, gout, or ankylosing spondylitis.

The diagnosis of these different disorders can be suggested by the pattern of specific joints involved, such as the knee joints, acromioclavicular joints, and interphalangeal joints in osteoarthritis; the metacarpophalangeal joints in rheumatoid arthritis; and involvement of the great toe in gout.
