Does RSD show up on a Bone Scan?

Reflex Sympathetic Dystrophy (RSD), now more commonly referred to as Complex Regional Pain Syndrome (CRPS), may not show specific changes on a standard bone scan. However, bone scans can reveal increased uptake in the affected area, indicating changes in bone metabolism or inflammation associated with CRPS. While a bone scan can support the diagnosis by showing these changes, it is not definitive for diagnosing RSD/CRPS on its own. Clinical evaluation and other diagnostic tools are typically necessary for a comprehensive assessment.
