Intro to MR - SAFETY
What do you do if a patient codes in the MRI scanner? (Choose all correct answers)
Select one or more:
a. Pull the patient out of the scanner and run the code on the MRI table.
b. Move the patient in the hallway to conduct the code
c. NEVER run the code in the MRI room
d. Wait until the scan is finished and pull the patient out of the MRI scanner. - Answer-b. Move the
patient in the hallway to conduct the code
c. NEVER run the code in the MRI room
What to do if a patient complains of heating or burns while in the scanner?
Select one:
a. Take the patient out of the room and investigate further
b. Put a cold compress on area and continue to scan.
c. Check on patient and tell them it will be ok.
d. Change the scan to run faster. - Answer-a. Take the patient out of the room and investigate further
What to do if a patient has an unknown implant?
Select one:
a. Ask the patient if they have had a MRI with the implant before and if so then OK to scan them
b. Scan the patient with the implant and tell them to let you know if they feel warm or burning
c. Tell them you don't scan anyone with implants in them.
d. The technologist or MRSO should investigate the implant and get written proof from the
manufacturer and approval from the radiologist that it is ok to scan this patient. - Answer-d. The
technologist or MRSO should investigate the implant and get written proof from the manufacturer and
approval from the radiologist that it is ok to scan this patient.
, Which MRI zone is has the MRI scanner in it? - Answer-Zone 4

What is a quench?
Select one:
a. The process of adding supercooled gasses to an MRI to produce magnetism
b. Damage to the MRI which causes exponentially increasing magnetic fields that can be very dangerous

supercooled gas from the magnetic coils.
Everyone needs an MRI pre- screening before entering an MRI environment. (T or F) - Answer-True
What is the "5 Gauss Line"?
Select one:

crossing - Answer-c. A fringe field line that may pose danger to patients with certain pacemakers
