A patient is moving in a magnetic field for 2 sec. and
experiences a magnetic spatial gradient of 200G/cm. What dB/dt
are they experiencing?
100T/s
Below the IEC limit
400T/s
10T/s
Below the IEC limit
,Page 2 of 227
The limit of dB/dt according to the IEC 60601-2-33 document
for movement in a static magnetic field is 3T/s. 200G/cm is =
2T/m and 2T/m divided by 2 seconds = 1T/m/s
This would be below the 3T/s IEC limit
You’re scanning a brain with a resonant frequency of 128MHz.
Your MR conditions state to only scan with a 1.5T unit in
normal mode. Can you meet the MR conditions?
Yes
No
No. (128MHz represent a 3T unit.)
Which of the following are true of a department according to the
ACR Manual on MRI Safety 2020? Select all that apply.

Patients are screened for threats in Zone 3
Ferrodetectors should be at the entrance of Zone 3
The entrance to zone 3 should have a keypad/badge system to
control access
MR screening forms should be filled out in zone 4
Ferrodetectors should be at the entrance of Zone 3
The entrance to zone 3 should have a keypad/badge system to
control access
Due to induced electrical fields produced in our patients due to
flowing blood and our static magnetic field, what can be
demonstrated?
Magnetophosphenes

All of the following
Nystagmus
Magnetohydrodynamic effect
Magnetohydrodynamic effect
Given the following parameters, which has the lowest heating
potential when dealing with TR, Pulse Duration, and flip angle?
TR= 2000 Pulse Duration=1ms Flip angle = 100
TR= 1500 Pulse Duration=2ms Flip angle = 160
TR= 2000 Pulse Duration=2ms Flip angle = 180
TR= 1500 Pulse Duration=1ms Flip angle = 180
