What Happens if You Move During an MRI?
MRI (Magnetic Resonance Imaging) is a medical imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the body’s internal structures. It is a safe and painless procedure that provides valuable information to help diagnose various medical conditions. However, it is essential for patients to remain still during the MRI scan to ensure accurate results. But what happens if you move during an MRI?
When a patient moves during an MRI, it can lead to blurred or distorted images, making it challenging for doctors to interpret the results accurately. In some cases, the entire scan may need to be repeated, increasing the time and cost of the procedure. Moreover, movement during an MRI can also cause artifacts, which are unwanted signals or patterns that can appear on the images, further hindering the diagnostic process.
To minimize the chances of movement during an MRI, patients are often provided with earplugs or headphones to reduce noise, as the loud knocking sounds produced by the machine can be unsettling. Additionally, some facilities offer sedation to patients who may have difficulty staying still for an extended period.
Here are some frequently asked questions about moving during an MRI:
1. Why is it important to remain still during an MRI?
Staying still ensures that the images obtained are clear and accurate, providing valuable diagnostic information.
2. What happens if I unintentionally move during the MRI?
If you accidentally move, the technologist will assess the images to determine if they are still usable. If not, they may need to repeat the scan.
3. Can I be restrained during an MRI to prevent movement?
If necessary, patients can be fitted with a strap or cushion to help keep them still. However, restraints are generally avoided unless absolutely necessary.
4. Will I feel any pain during the MRI scan?
MRI itself is painless. However, some patients may experience discomfort due to lying still in a confined space or from the noise produced by the machine.
5. What if I need to sneeze or cough during the MRI?
Inform the technologist beforehand, and they will pause the scan if necessary to allow you to cough or sneeze.
6. Can I listen to music during an MRI to help me relax?
Many MRI facilities provide headphones or earplugs that allow patients to listen to music during the procedure.
7. Can I move slightly to get more comfortable during the scan?
It’s best to discuss any discomfort or need to move with the technologist before the scan begins. They may be able to make adjustments to ensure your comfort.
8. What happens if I’m unable to stay still for the entire scan?
In some cases, sedation may be offered to patients who struggle with anxiety or difficulty remaining still. This should be discussed with your doctor beforehand.
9. How long does an MRI scan usually take?
The duration of an MRI scan varies depending on the area being imaged. It can range from 15 minutes to an hour or more.
In conclusion, moving during an MRI can lead to distorted images and artifacts, making the interpretation of results challenging. It is crucial to remain still during the procedure to ensure accurate imaging. Patients should communicate any discomfort or need to move with the technologist to find solutions that allow for a successful and comfortable MRI experience.
