Why must patients be screened for implants before an MRI scan?
✔✔ Some implants can heat up, malfunction, or move, causing harm
What safety precaution should be taken for patients with pacemakers?
✔✔ MRI should generally be avoided unless the pacemaker is MRI-compatible
Why is it important to remove all metallic objects before entering the MRI room?
✔✔ Even small objects can be pulled into the magnet, posing a safety risk
What should a patient do if they experience discomfort or heating during an MRI scan?
✔✔ Inform the MRI technologist immediately to stop the scan if necessary

,Why are hearing protection devices required for MRI scans?
✔✔ The scanner produces loud noises that can damage hearing over time
What is the purpose of the five-gauss line in MRI safety?
✔✔ It marks the boundary beyond which the magnetic field may affect medical devices
Why should MRI staff be cautious with oxygen tanks in the scan room?
✔✔ Oxygen tanks are ferromagnetic and can be pulled into the magnet
How can MRI technologists prevent radiofrequency (RF) burns?
✔✔ Ensure that cables and patient skin do not form conductive loops
