Bone Scan For Arthritis
My WBC is 3. I have bilater bone pain in almost all my joints. Does that warrant a bone scan. Could arthritis affect all the joints at once?
A condition where there is progressive degeneration of one or more joints. Symptoms may include joint pain, swelling, decreased motion, and stiffness. The two most common types of arthritis are osteoarthritis, which is associated first with articular cartilage breakdown with a component of inflammation, and rheumatoid arthritis, which is a systemic autoimmune disorder that affects joint linings first and secondarily ...Read more
Several reasons: Not everything that causes symptoms similar to arthritis is actually arthritis. Most helpful bone scan is two phases, early soft tissue and delayed bone. Soft tissue of joints can show which joints are hyperemic or active. Delayed images may be normal. Multifocal osteomyelitis (crmo), metastatic disease, osteorotic bone with fractures, etc. Are causes. Bone scan can rule out mimicers of arthritis. Read moreSee 2 more doctor answers

Cause of pain: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton. Bone scan very sensitive but not specific. Bone scan can show increased bone metabolism and source of pain. Increased uptake is seen in fractures, tumors, infection, etc. If scan localizes pain area, then correlative imaging with MRI or ct scan will help your doctor in treating pain.

Not usually: T scores are for patients over 18 yr and z scores for children under 18 yr. The controls for children are bases on ages, color, and sex. The t scores are compared to other adults. Dexa centers who perform studies on children have software to generate both values. T scores cannot be used accurately for children and z scores not in adults. Read moreSee 2 more doctor answers
Tracers..: The tracers are different. Bone scan usually uses TcMDP and PET scan uses F18-FDG (glucose). The bone scan is good for showing osteoblastic bone lesions and shows increased bone activity around a metastasis but not the actual metastasis itself. The PET can show glucose uptake in the actual tumor itself. PET is better for lytic bone lesions. CT part of PET/CT can show lytic and blastic lesions. Read moreSee 1 more doctor answer
Increased uptake: Osteoblastic is term for new bone formation usually describing radiographic appearance. Translated to bone scan this means increased uptake which can be bone repair of infection, fracture, or tumor. Bone scans are very sensitive to bone turnover but not specific. Some primary bone tumors are osteoblastic in that they form bone. Nonarticular means focus of uptake away from a joint. Read moreSee 2 more doctor answers
Need therapy: Reflex sympathetic dystrophy is characterized by group of symptoms including pain (often "burning" type), tenderness, and swelling of an extremity associated with varying degrees of sweating, warmth and/or coolness, flushing, discoloration, and shiny skin. May be associated with injury to the nerves, trauma, surgery. Some therapy medication NSAIDS or sympathetic blockade. Read moreSee 2 more doctor answers
