What is the primary purpose of using a sandbag in imaging?

The primary purpose of using a sandbag in imaging is to stabilize the femur not being scanned. When performing imaging studies, particularly in areas involving the pelvis or lower limbs, it is crucial to keep the patient still to obtain clear and accurate images. By placing a sandbag on the limb that is not being imaged, the technologist helps to minimize movement and prevent any accidental positioning changes that could compromise the quality of the scan. Stability is essential in imaging procedures to ensure that anatomical structures are properly visualized and that diagnostic accuracy is maintained.

While improving image quality, providing comfort, and enhancing equipment mobility may also be associated with certain imaging practices, they do not directly represent the primary function of a sandbag in this context. The emphasis here remains firmly on stabilization for optimal imaging outcomes.
