UPDATE 2026/2027
Which of the following concerns can be caused by the
time-varying gradient magnetic field?
a. All of the choices
b. Arrhythmia
c. Muscle fatigue
d. Anaphylaxis
b. Arrhythmia
Typically, where is the area surrounding the MR unit with
the highest spatial magnetic gradient field?
a. At the 5 Gauss line
,Page 2 of 262
b. MR table
c. Isocenter
d. MR table control panel
d. MR table control panel
When we reach isocenter, no spatial gradient is detected.
Which of the following is true of stainless steel? Select all
correct answers.
a. It is not used in medicine
b. All are non-ferrous
c. All will demonstrate rotational force
d. All will cause artifacts in our image
d. All will cause artifact in our image
3 types of stainless steel:
Austenitic: non-ferrous that is most commonly used.
,Page 3 of 262
Ferritic: ferrous metal; not common
Martensitic: ferrous metal used in medicine. High levels of
carbon and can be tempered. Resistant to corrosion.
Rotational force is strongest where?
a. On the table
b. At the control panel on the MR unit
c. Isocenter
d. It is uniform everywhere
c. Isocenter
What types of cryogen are used in a duel cryogen system?
a. Helium and hydrogen
b. Helium and nitrogen
c. Helium and carbon dioxide
d. Helium and oxygen
, Page 4 of 262
b. Helium and nitrogen
Uses helium to keep the superconducting wires cold and
nitrogen is a backup to keep the helium in its liquid state
to reduce the burn off of helium.
A deflection of 90 degrees due to translational force
indicates how much force is experienced in the implant?
a. 0.5 gravity force
b. 2 gravity force
c. 1 gravity force
d. Undetermined
d. Undetermined
Deflection of 45 degrees indicates equal balance between
the gravity place on the implant and the translational
force experienced by the implant. With 90 degrees, we
cannot tell how much force the implant is experiencing; it
will be greater than 2G.
