Which method decreases the risk of movement during an MRI scan?

Using straps and cushions is an effective method to decrease the risk of movement during an MRI scan. Movement can significantly affect the quality of the images obtained during the procedure, potentially leading to artifacts or incomplete scans. Straps and cushions help to stabilize the patient and maintain a comfortable position, minimizing the likelihood of involuntary movements. By enhancing stability, these methods not only improve the image quality but also contribute to a more efficient scanning process, potentially reducing the need for repeat scans.

Methods such as sedatives may also reduce movement, but they carry risks and can complicate patient management. Adjusting scan times may help accommodate patient needs but does not address the root cause of movement. Not informing the patient tends to increase anxiety and may lead to more movement, as patients who are unaware of what to expect can become restless or uncomfortable during the scan. Thus, using straps and cushions is a straightforward and effective approach to mitigating movement-related issues in the MRI setting.
