What is a common precaution for patients undergoing an MRI scan?

Patients should lie still during an MRI scan to ensure the clarity and accuracy of the images being produced. Any movement can lead to artifacts and blurring in the images, potentially compromising the diagnostic information that the scan provides. MRI technology relies on capturing detailed images of the body's internal structures, and even slight shifts can impact the end result.

Remaining motionless for the duration of the scan allows for the most precise data collection, making it easier for radiologists to interpret the findings accurately. This practice is crucial for obtaining high-quality images, ensuring that any abnormalities or relevant anatomical features are clearly visualized. Thus, emphasizing the importance of stillness during the procedure is fundamental in MRI safety protocols and patient instructions.
