Let's Test Your MRI Safety Knowledge

The statement suggests that the individual will seek clarification from the relevant staff or personnel before entering a Magnetic Resonance (MR) environment if they have any questions. This indicates a proactive approach to ensuring safety and understanding the necessary precautions in such an environment. Therefore, the correct answer is true.

MRI stands for Magnetic Resonance Imaging. This medical imaging technique uses a strong magnetic field and radio waves to generate detailed images of the body's internal structures. It is commonly used to diagnose and monitor a variety of medical conditions, as it provides clear and precise images of organs, tissues, and bones.

Bringing electronics such as a laptop, cell phone, or pager can result in damage to your device. Laptop hard drives are easily corrupted or erased by the magnetic field. The magnetic field can also drain the battery or damage other electronic devices.

To evaluate any potential health risks for entering an MR-environments such as specific medical conditions, pregnancy, surgical implants, pacemakers, neurostimulators, cochlear implants, ferromagnetic or unidentified clips, pumps, surgical screws, metal or unidentified bodies near the eyes, shrapnel, etc. need to be evaluated my hospital personnel before entering an MR area

Most MRI Magnets have oval field lines or regions around them indicating the magnetic field (colors vary on each site). The inner set of lines usually indicate 50 Gauss and the outer lines usually indicate 5 Gauss. 5 Gauss is enough to turn a metallic object into a projectile or cause damage.

Numerous research studies show no health issues as a result of prolonged exposure to a magnetic field by an MRI. There are other hazards such as metallic objects or quenches of which to be aware.

Only for emergency use when someone is pinned to the magnet by an object or is incurring harm as a result of the magnetic field

Quench refers to an intentional or unintentional release of supercooled gas from the magnet coils in an MRI. This can occur due to various reasons such as a power failure or a malfunction. When a quench happens, the sudden release of gas causes the magnet to lose its superconductivity, resulting in a rapid increase in resistance and the generation of heat. This can be dangerous as it can damage the MRI and potentially harm nearby individuals if not properly handled.

The emergency stop button is designed to ensure the safety of individuals in case of an emergency situation. It functions by immediately cutting off all electrical power to the magnet and stopping the movement of the magnet. This action helps to prevent any potential harm or damage that could occur due to the continued operation of the magnet.

None of the items above are safe to bring into an MR environment. Metal keys or rings can become projectiles from the force of the magnetic field. Electronics such as cell phones can be damaged by the MR field. The magnetic strips on credit cards, hotel keys, and passports will be damaged if near the magnetic field.
