What is the best way to control voluntary motion during imaging?

1. Immobilization

2. Careful explanation

3. Short exposure time

4. Physical restraint

The correct answer is: Careful explanation

The best way to control voluntary motion during imaging is to provide a careful explanation to the patient. When patients understand the procedure and the importance of remaining still during the imaging, they are more likely to cooperate and hold their position. Effective communication can alleviate anxiety and encourage patients to follow instructions, which is crucial for obtaining clear and accurate images. In contrast, while immobilization and physical restraint can be effective methods in certain situations, they may not always be practical or comfortable for patients. Using short exposure time is beneficial primarily for minimizing motion blur due to involuntary motion rather than voluntary movements. Therefore, ensuring the patient is well-informed and at ease tends to yield the best results in controlling voluntary motion during imaging procedures.
