Movement during an MRI scan can compromise the quality of the images due to the sensitivity of the magnetic field and the precise nature of the imaging process. Research on quantum tunneling and magnetic fields further emphasizes the importance of maintaining a stable environment to ensure accurate and clear imaging results. Therefore, it is crucial for patients to remain as still as possible during MRI scans to avoid any potential interference.

Magnetic Resonance Imaging (MRI) is a widely used diagnostic tool in medical practice. It employs strong magnetic fields and radio waves to generate detailed images of the organs and tissues within the body. A common question among patients undergoing MRI is whether they can move while inside the MRI tunnel. This article explores the implications of movement during MRI scans, drawing on relevant research to provide a comprehensive understanding.

The Basics of MRI

MRI machines create a powerful magnetic field around the patient. This field aligns the protons in the body, and radio waves are then used to disturb this alignment. When the radio waves are turned off, the protons realign, emitting signals that are used to create images. The quality of these images is highly dependent on the stability of the magnetic field and the absence of external interference.

Impact of Movement on MRI Quality

Movement during an MRI scan can significantly affect the quality of the images produced. The magnetic field and radio waves are finely tuned to capture precise details, and any movement can cause blurring or distortions in the images. This is particularly critical in diagnostic imaging, where clarity and detail are paramount for accurate diagnosis.

Quantum Tunneling and Magnetic Fields

Research on quantum tunneling in magnetic fields provides insights into the sensitivity of magnetic resonance to external factors. For instance, the study “Tunneling in a magnetic field” highlights how quantum tunneling across a static potential barrier is highly sensitive to the form of the potential barrier and the presence of a magnetic field1. This sensitivity underscores the importance of maintaining a stable environment during MRI scans to avoid interference with the magnetic field.

Interference from Magnetic Molecules

Another study, “Interfering Tunneling Paths through Magnetic Molecules on Superconductors,” discusses how magnetic adsorbates can induce resonances that interfere with tunneling paths2. This research, although focused on superconductors, illustrates the broader principle that magnetic fields and their interactions are delicate and can be easily disrupted by external factors, including movement.

Physically, are you able to move in an MRI scanner? Yes of course you can!!

Should you? Probably not!!

You’re probably in the scanner to get some good diagnostic medical images of your body, either for your health or for some research that has been deemed useful by an ethics committee. You’re wasting your time and everyone else’s if you dance along to the song on the radio because you’ll get blurry pictures. For this reason we’ll usually put loads of padding around the area we want to image – to help and remind you to keep still.

However there’s another excellent reason why not. You’re inner ear contains a set of highly tuned balance sensors that use earth’s gravitational and magnetic fields to tell you which way up you are. You can test these by closing your eyes while on a spinning office chair or while going round a corner in a bus or car (as long as you’re not the driver). Moving through magnetic field lines has a similar effect – and might make you dizzy or nauseus. So please don’t be sick in the scanner.
