Questions and Answers Already Graded
A
What is the primary concern when bringing metallic objects near an MRI scanner?
✔✔ They can become dangerous projectiles due to the strong magnetic field
Why must MRI patients be screened for implanted medical devices?
✔✔ Some implants can malfunction or heat up, causing injury
What should be done if a patient experiences discomfort during an MRI scan?
✔✔ Stop the scan and assess the patient's condition immediately
Why is it important to use MRI-safe equipment in the scanner room?
✔✔ Non-MRI-safe equipment can be pulled into the magnet and cause injury
What is the safest way to transport a critically ill patient into the MRI room?
✔✔ Use MRI-compatible stretchers, ventilators, and monitoring devices
1
,Why is hearing protection required during an MRI scan?
✔✔ The scanner produces loud noises that can cause hearing damage over time
What should be done if a patient with a pacemaker needs an MRI?
✔✔ Consult a cardiologist and determine if the pacemaker is MRI-conditional
Why must MRI staff verify the type of aneurysm clips before a scan?
✔✔ Some clips are not MRI-safe and can shift, causing serious harm
What is the function of the MRI safety zones?
✔✔ To control access and minimize exposure to the magnetic field
Why should pregnant patients consult a physician before an MRI?
✔✔ The potential effects of MRI on fetal development are not fully understood
What should an MRI technologist do if a fire alarm goes off in the MRI suite?
✔✔ Follow emergency protocols and ensure all personnel and patients evacuate safely
2
,Why is it necessary to check for metallic foreign bodies in patients with a history of metalwork?
✔✔ Small metal fragments in the eyes or body could move and cause severe injury
What is the best action if a patient experiences claustrophobia during an MRI scan?
✔✔ Pause the scan, reassure the patient, and consider sedation if needed
Why should non-MRI personnel receive safety training before entering the scanner room?
✔✔ To prevent accidents involving magnetic objects and medical devices
What should be done if a ferromagnetic object becomes stuck in the MRI scanner?
✔✔ Secure the area and contact trained personnel to safely remove the object
Why must contrast agents be used cautiously in patients with kidney disease?
✔✔ Some contrast agents can cause nephrogenic systemic fibrosis in patients with poor kidney
function
What is the safest action if a patient reports a burning sensation during an MRI scan?
✔✔ Stop the scan immediately and check for RF burns or heating from implants
3
, Why is it important to maintain a safe distance from the magnet bore when handling tools?
✔✔ Even small objects can be pulled in forcefully, posing a serious safety risk
What should be done if an MRI patient has a history of allergic reactions to contrast agents?
✔✔ Pre-screen for allergies and consider alternative imaging methods or premedication
Why is it critical to monitor patients with severe medical conditions during MRI scans?
✔✔ Some conditions may worsen due to the scan, requiring immediate intervention
What is the main reason for restricting food and drinks in the MRI suite?
✔✔ Spills can damage equipment and create hygiene concerns
Why must MRI-compatible fire extinguishers be used in the scanner room?
✔✔ Regular extinguishers contain ferromagnetic materials that can become projectiles
What should a patient do if they have concerns about an MRI scan?
✔✔ Discuss their concerns with the MRI technologist before the scan begins
