Dual energy X-ray absorptiometry (DXA) is the recommended reference standard for measuring muscle mass in clinical practice and research due to its balance of feasibility, accuracy, safety, and cost.

If you need to measure your muscle mass accurately, ask for a DXA scan. It is the current best balance of accuracy, safety, and cost. While other methods like BIA scales exist, they are less accurate for individuals. CT and MRI are too expensive and expose you to more radiation (CT) or are less available.

GoodSupportsHIGH confidence
Based on the feasibility, accuracy, safety, and low cost, dual energy X-ray absorptiometry can be considered as the reference standard for measuring muscle mass.
