MRI: Lesson 1 - Introduction, Screening and Safety Questions and Answers with Certified Solutions

MRI: Lesson 1 - Introduction, Screening and Safety Questions and Answers with Certified Solutions What is the main safety concern for patients with metallic implants during an MRI scan? Metallic implants can move, heat up, or interfere with image quality due to the strong magnetic field. Why is it essential to verify the type of implant a patient has before performing an MRI? Some implants are MRI-safe, while others can be hazardous or cause image distortions. How does the MRI magnetic field affect credit cards and electronic devices? The magnetic field can erase credit card data and permanently damage electronic devices. Why are patients advised to inform the technologist if they have ever had metal fragments in their body? Small metal fragments, especially in the eyes or brain, can shift or heat up, causing serious injury. 2 What should be done if a patient with a suspected metal foreign body needs an MRI? A preliminary X-ray may be performed to confirm the presence and location of the metal. Why is it dangerous for unauthorized personnel to enter the MRI room? The powerful magnetic field can turn ferromagnetic objects into projectiles, causing serious injuries. What is the purpose of the MRI-compatible emergency equipment in the MRI room? To ensure that life-saving interventions can be performed safely without interfering with the magnetic field. Why should patients remove drug patches before an MRI scan? Some patches contain metallic backing that can heat up and cause burns. What is the best way to prevent safety incidents related to the MRI magnetic field? Strict adherence to screening protocols and keeping unauthorized metallic objects out of the MRI room. 3 Why must MRI rooms have special non-magnetic stretchers and wheelchairs? Standard metal medical equipment can be pulled into the magnet, posing a severe risk. What should an MRI technologist do if a patient experiences discomfort or pain during the scan? Stop the scan and check on the patient immediately to ensure their safety. How does the magnetic field strength of an MRI scanner compare to everyday magnets? MRI scanners have much stronger magnetic fields, thousands of times more powerful than refrigerator magnets. Why is it important to assess patients with aneurysm clips before an MRI? Some older aneurysm clips are not MRI-safe and could move, leading to life-threatening complications. What is the primary reason for MRI staff to wear non-magnetic identification badges? Metal badges could be pulled toward the magnet, creating a safety hazard. Why must all MRI staff undergo extensive safety training? 4 To prevent accidents by ensuring they understand and follow all MRI safety protocols. What should be done if a fire occurs inside an MRI room? Only use MRI-compatible fire extinguishers and
