What is the purpose of an MRI safety zone system?
✔✔ To control access and ensure only properly screened individuals enter areas with magnetic
field risks.
Why must all metallic objects be removed before entering the MRI room?
✔✔ Because the strong magnetic field can turn them into dangerous projectiles.
What type of material is considered MRI-safe?
✔✔ Non-ferrous materials such as titanium, plastic, and specific medical-grade alloys.
Why is it dangerous to bring oxygen tanks into an MRI room?
✔✔ They can be pulled into the magnet, causing serious injury or damage.
How can MRI personnel verify that a patient does not have a metallic implant?
✔✔ By reviewing medical history, conducting thorough screening, and using approved
documentation.
1
,What should a staff member do if they suspect a patient has an undisclosed implant?
✔✔ Stop the scan and consult an MRI safety officer or radiologist before proceeding.
Why are patients with pacemakers typically not allowed in MRI scanners?
✔✔ The magnetic field can interfere with or damage the device, leading to serious
complications.
How does an MRI scanner affect credit cards and electronic devices?
✔✔ The magnetic field can erase data and permanently damage electronic components.
Why is proper hearing protection required for MRI scans?
✔✔ The machine produces loud noises that can cause hearing damage over time.
What is the function of an MRI quench?
✔✔ To rapidly release liquid helium in case of an emergency, shutting down the magnet.
Why must an MRI room have proper ventilation during a quench event?
2
, ✔✔ To prevent asphyxiation from helium displacement of oxygen.
How should an emergency responder approach an MRI-related accident?
✔✔ Only after confirming the magnet is off or receiving clearance from MRI personnel.
What can happen if a metal object is left undetected in a patient’s clothing?
✔✔ It can heat up and cause burns due to radiofrequency energy absorption.
Why should pregnant MRI workers avoid staying in the scanner room during imaging?
✔✔ To minimize exposure to potential, although unproven, risks from the magnetic field.
How should non-MRI personnel be educated on MRI safety?
✔✔ Through mandatory safety training and strict access controls to restricted zones.
What is the safest way to transport a patient on a stretcher to an MRI room?
✔✔ Using an MRI-compatible stretcher made of non-magnetic materials.
Why is patient screening necessary before every MRI scan, even for repeat patients?
