Which forearm is typically used for BMD scans unless indicated otherwise?

• A. Dominant forearm
• B. Non-dominant forearm
• C. Left forearm
• D. Right forearm

Answer: (B)

The non-dominant forearm is typically used for bone mineral density (BMD) scans for several reasons. Primarily, it minimizes the effects of physical activity on the results. The dominant forearm is usually subjected to more physical stress and usage, which can potentially lead to increased bone density due to the higher levels of mechanical loading. By using the non-dominant forearm, practitioners aim for a more stable and representative measure of bone density that is less influenced by regular daily activities.

Additionally, using the non-dominant forearm helps to standardize the procedure across various patients, ensuring comparable results. This standardization is important in clinical settings, particularly when making assessments regarding osteoporosis or other conditions that affect bone health. Employing the non-dominant forearm allows for a consistent baseline, which is crucial for reliable diagnosis and treatment planning.
