MRI SAFETY QUIZ

A person with altered mental status is sent from the emergency room for an urgent MRI, but no family, prior scans, or medical history are available. What should you do to ensure reasonable safety for the exam?

• Call the ER physician and ask if there are any reasonable alternatives to MRI in light of the absent history, and if not, go ahead and perform the scan as ordered.

• 1. Use a hand-held ferromagnetic metal detector to exclude a dangerous implant or foreign body

  
  

• 1. Obtain x-rays of the head & neck, chest, and abdomen/pelvis as a screening procedure

  
  

• 1. Refuse to do the MRI until a full medical history can be obtained.

  
  

Common clinical MRI scanners use magnetic fields of

• 1.5T

• 3T

• 1.5 AND 3.5T

Strict safety protocols are essential, and include the implementation of metal detectors and the verification of MRI compatibility of implanted medical devices.

• True

• False

Optimizing signage inside and outside MRI suites with more specific and clear warnings using universally recognized symbols and explicit danger messages can significantly reduce risks

• True

• False

•The radiofrequency (RF) field (B1) can lead to tissue heating and cause burns, especially with high specific absorption rate (SAR) levels, and can induce currents in metallic implants causing heating or malfunction.

• True

• False

•Implementing advanced and clearly defined technical symbols is NOT essential to ensure safety in MRI environments.

• True

• False

An example of effective signage could be the "Danger MRI" sign, which immediately communicates the zone's danger.

• True

• False

This Magnet Is Always On!” In fact, investigations into incidents involving large ferromagnetic objects like oxygen cylinders, chairs, IV poles, and wheelchairs revealed that the hospital staff involved believed that the powerful magnetic field was only activated during the MRI procedure

• True

• False

Implementing signs in MRI facilities not only underscores the importance of creating accessible and safe environments for all, but also leverages the unique neural capabilities of blind individuals to ensure complete and accurate understanding of safety information.

• True

• False

•Including instructions to scan a QR code for additional safety information and procedures before entering MRI facilities may be a good idea.

• True

• False
