A patient has a brain aneurysm clip that is conditional up to 700 G/cm. Is this patient safe to be
scanned when only considering the static magnetic field?
a. Yes
b. No
a. yes (aneurysm clip does not come within the 7T/m field)
700 G/cm = 7 T/m
(100 G/cm = 1 T/m)
What would we expect to see when a malfunctioned quench causes helium to leak into the MR
room? Select all that apply.
a. Decrease in the magnetic field strength
b. Increase in room temperature
c. Increase in room temperature
d. Decrease in room temperature
a, d

b. Titanium
b. Titanium (60% less artifact than stainless steel)

a. Exposure up to 8T
b. Exposure up to 2T
c. Exposure up to 10 T
d. Exposure up to 4T
a. 8T
A patient is having an MR brain scanned in first level controlled mode with a receive only coil.
We know that the SAR will not exceed which of the following?
a. 2.0 W/kg
b. 8 W/kg
c. 3.2 W/kg
d. 4.0 W/kg
c. 3.2 W/kg
What is the limit of the static magnetic field for patients >1 month old?
a. 2 T
b. 4 T
c. 10T
d. 8 T
d. 8
Which of the following is true of gad associated plaques? Select all that apply.
a. This is a common occurrence in MRI
b. The same thing as NSF
c. Occurs when gad is ingested
d. Not related to renal compromised patients.
d. Not related to renal compromised patients

,Which of the following are true of the static magnetic field? Select all that apply.
a. Conditional implants will not be impacted by the magnetic field strength, only the spatial
magnetic gradient.
b. Will demonstrate a growing magnetic field as we approach the MR unit.
c. Will magnetize our patient at isocenter
d. Will demonstrate some attractive force on all metals.
b, c
A patient has shown a maximum heat increase of +0.6 degrees Celsius at 1.5 T & 3.0 T. This
increase is considered safe under the MR standards put in place.
a. True
b. False
a. True
A sequence is run with peak unweighted sound pressure of 120dB. Is this within FDA
regulation?
a. Yes
b. No
a. Yes
What is the limit of the static magnetic field for patients <1 month old?
a. 3 T
b. 2 T
c. 8 T
d. 4 T
d. 4 T
Which of the following are NOT true of the static magnetic field? Select all that apply.
a. It contains magnetic flux lines that can travel through standard walls
b. Rotational force will cause the torquing of ferrous objects as they interact with magnetic flux

c. It has been known to cause pregnancy related issues
d. It is the cause of magnetohydrodynamic effects only when the table is moving
b, c, d
Which of the following is considered a passive noise control technique?
a. Anti-noise headphones
b Earplugs
c. All of the choices
d. Quiet gradient sequences
b. Earplugs
How does a deep brain stimulator without a generator pose the greatest threat to a patient?
a. Translational force
b. Heating/burning
c. Peripheral nerve stimulation
b. Heating/burning
The long leads can generate heat and burn our patient. The translational force may not be as
threatening as the burning risk.
Medtronic deep brain stimulator has a SAR limit of 0.1 W/kg and a static magnetic field of
3.0T or less.
According to the ASTM F2503 document, the MR environment refers to what?
a. An area that contains the Faraday shield and the 5 Gauss line
b. Anything within the 5 Gauss line
c. Zone III & IV
d. Zone IV
a. An area that contains the Faraday shield and the 5 Gauss line.
