MRI scanners use a powerful magnet to create a magnetic field, and because of its strength, it can affect objects made of metal. You cannot move while in the MRI machine because movements of any kind can disrupt its powerful magnet.
Even small objects like jewelry, hair pins, and eyeglasses can be pulled towards the MRI scanner. In addition, sudden body movements can cause you to lose your positioning in the scanner, resulting in incomplete images.
Another important reason is that patients must keep their head and body very still during the scanning process, as any movement can blur the image and result in an inaccurate picture. Additionally, all movements can create loud noises in the process, which can be both disruptive and distracting for the patient.
Finally, if a patient does move during an MRI scan, it might take more time and require more scans to get enough quality images.

What happens if I move during an MRI scan?
If you move during an MRI scan, it can result in a blurrier image, reduced accuracy, and/or a longer scan time, depending on how much you move. While an MRI technician will be monitoring your movements to prevent you from moving too much, sudden, jerky, or repeated movements can still affect the quality of the scan, since the scanner needs you to remain still in order to get accurate images.
Moving during an MRI scan can require a technician to restart the scan, which can lead to longer scan times and higher costs. It is important to remain as still as possible during the entire MRI procedure to ensure the best images.
Do you have to lay flat during an MRI?
No, you don’t have to lay flat during an MRI. Depending on the type of MRI that you have, you may have to remain still in a variety of positions. Some procedures require you to lie on your back, while others require you to lie on your side.
If you are having a cardiovascular MRI, you may be asked to lie on your left side. During some MRIs, you may be asked to sit up or even stand up. In some cases, you may be able to move your arms, legs, or head during the procedure if needed.
Most people have to remain still for the duration of the MRI, however.
Can I open my eyes during MRI?
No, it is not safe to open your eyes during an MRI. An MRI creates a strong magnetic field that can attract metal objects and cause serious accidents. This includes glasses, watches, jewelry, and other metal objects, which can all potentially cause harm if you open your eyes during the MRI.
Additionally, an MRI can create a bright light that could potentially damage your eyes if you try to open them during the procedure. For these reasons, it is important to keep your eyes closed throughout the entire MRI procedure.
Are upright MRI accurate?
Yes, upright MRI scans are accurate when used to diagnose a variety of conditions, including joint and spine conditions, such as fractures, nerve damage, and spinal stenosis. Upright MRI scans help to create a three-dimensional image of the patient’s spine, joints, and discs.
This image allows doctors to have a better view of the patient’s anatomy, which can lead to a more detailed diagnosis and better care plan. Upright MRI scans can also help detect any narrowing of the spinal canal which can be indicative of serious conditions such as disc herniation or spinal stenosis.
Additionally, upright MRI scans can detect any changes in the size and shape of the discs and vertebral bodies which can be indicative of disc degeneration or other structural issues. In short, upright MRI scans are accurate and helpful for diagnosing a variety of conditions, both minor and serious.
Is standing MRI the same as lying down?
No, standing MRI is not the same as lying down MRI. Standing MRI is a more recent technology that allows people to remain standing while they undergo an MRI scan. This type of scan is beneficial as it eliminates the need for people to stay in uncomfortable positions over a long period of time, reducing the risk of muscle fatigue, back pain and other issues associated with lying down for extended periods.
Additionally, since a person is in an upright position, it allows more accurate images of internal organs and muscles related to standing, such as the spine and heart. While traditional MRI scans produce clear and detailed images, Standing MRI provides more detailed images that are necessary for certain types of medical examinations.
Finally, a standing MRI can help to reduce the risk of motion artifacts, as people are less likely to move during the scan.
How close is the MRI to your face?
The exact distance of an MRI from your face can vary depending on the type of MRI being performed. For example, if a Cervical Spine MRI is being done, the patient’s head will typically be placed into the MRI scanner in a resting position and the machine will be placed as close as possible to the face.
However, for an MRI of the brain, the patient’s head will usually need to be positioned with the chin lower than the forehead and the machine will be placed at a slight distance from the face. Generally, an MRI machine does not come into direct contact with the face, although for certain advanced studies, such as a functional MRI, the patient’s face may be positioned closer to the scanner.
What are the after effects of an MRI?
The after effects of an MRI depend on the patient. Most people experience no after effects from an MRI. However, in some instances, some people may experience dizziness, nausea, or pain from the injections used during the scan.
For people who experience these symptoms, it may be helpful to drink fluids and rest for a few hours. In rare cases, an allergic reaction can occur. This reaction may cause itching, hives, swelling and a possible rash.
If you experience any of these symptoms after an MRI, it is important to contact the imaging center so they can provide the appropriate treatment.
In some cases, a metallic taste may be experienced after an MRI. This is due to the gadolinium injection that is used to enhance the images during the scan. This taste will usually subside on its own.
In most cases, MRIs are safe and have no lasting effects or side effects. It is important to always consult with a healthcare provider prior to and after an MRI, in order to make sure that any side effects or reactions can be identified and treated promptly.
Why are my eyes bloodshot after MRI?
Your eyes may appear bloodshot after an MRI because of the strong magnet used in an MRI. During the MRI scan, a powerful magnet may create a small amount of heat near the head, which can cause the eyes to become irritated.
This may also be due to the bright light used during the scan. The bright light used in an MRI scanner may constrict the blood vessels in the eyes and make them appear red or slightly bloodshot. Additionally, the long period of time your eyes may need to remain open for the scan may also cause them to become bloodshot.
Allergy, fatigue, or dry eyes are other possible reasons for having bloodshot eyes. If you are concerned about the bloodshot eyes after an MRI, it is best to talk to your doctor about this.
What are two major disadvantages of MRI scans?
One of the major disadvantages of MRI scans is the cost. While the cost of MRI scans varies greatly depending on the region and institution, they are generally more expensive than other imaging exams.
Additionally, the cost of an individual scan will often be higher if sedation or other special arrangements are necessary.
Another issue is that MRI scans can cause discomfort for some patients. For those who suffer from claustrophobia, the confined space of the MRI machine can be particularly frightening. Additionally, the loud noises associated with the scan can be uncomfortable.
Furthermore, due to the use of magnets, patchy tattoos or certain medical implants can cause interference with the scan and cause discomfort.
