1. Which of the following are bioeffects associated with the time-varying gradient magnetic
field? Select all that apply.
a. Peripheral nerve stimulation
b. Heating
c. Magnetohydrodynamic effect
d. Magnetophosphenes - Correct Answer: a, d
There's been no evidence of heating associated with the time-varying gradient fields.
Magnetophosphenes and peripheral nerve stimulation have to do with a fast changing magnetic
field. We find this with the time-varying gradient field. Magnetohydrodynamic effect has to do
with the static magnetic field and flow potential.
2. Which of the following is true of a 3T MRI? Select all that apply.
a. It will produce more stimulation at isocenter than other field strengths.
b. Will have a larger maximum spatial gradient than a 1.0 T unit
c. It will have a higher whole body SAR limit in normal mode than the normal mode at a 1.5 T
d. Have more chance for peripheral nerve stimulation than at 1.5T - Correct Answer: b. Will
have larger maximum spatial gradient than a 1.0 T unit.
3. Passive metallic implants <2cm are not expected to heat up during image acquisition.
,a. True
b. False - Correct Answer: a. True
4. The strength of the gradient field will reach a maximum strength of what?
a. 10-30 mT
b. 40-60 mT
c. 20-40 mT
d. 0-20 mT - Correct Answer: c. 20-40 mT
(0.04 T = 40 mT)
4. Which of the following describes the translational magnetic field demonstrated to a patient
at a specific location?
a. dB/dt
b. dB/dx
c. dB/dt*B - Correct Answer: b. dB/dx
5. The static magnetic limit for the general public for any body part is set to what?
a. 4T
b. 400 mT
c. 2T
d. 200 mT - Correct Answer: b. 400 mT (0.4T)
6. The quench vent outside the MR facility is inspected by whom?
a. MR tech
b. Manufacturer engineer
,c. Facility engineer
d. MRMD - Correct Answer: c. Facility engineer
(The quench vent in the MR room is inspected by the manufacturer engineer)
7. What type of gad contrast has been shown to cause falsely low serum calcium laboratory
values?
a. Linear ionic
b. Linear non-ionic
c. Macrocyclic
d. There is no correlation - Correct Answer: b. Linear non-ionic
8. Pregnant patient should never receive contrast.
a. True
b. False - Correct Answer: b. False
9. We are scanning a cardiac MRI. What body part would we expect to experience peripheral
nerve stimulation?
a. Knee
b. Foot
c. Heart
d. Head - Correct Answer: d. Head
10. To date, most mechanical valves are unsafe at field strength of 3.0 T.
a. True
b. False - Correct Answer: b. False
, All tested heart valves are conditional at field strengths of 4.7 T or less
11. Where would you expect to see the most heating on the IVC filter?
a. the end of the wires
b. the middle of the wires
c. at the top of the filter - Correct Answer: a. the end of the wires (smallest diameter)
12. Which of the following will increase the chance that an implant will cause a burn in our
patient? Select all that apply.
a. A tattoo that uses yellow ink is within the RF field
b. A bullet is within the RF field
c. Part of a temporary epicardial pacing wire is outside the patient's body.
d. A hip replacement is found in the RF field - Correct Answer: c. Part of a temporary
epicardial pacing wire is outside the patient's body.
13. All the zones need to be represented with signage except:
a. Zone I
b. All the zones must be represented with signage
c. Zone II
d. Zone IV
e. Zone III - Correct Answer: b. All the zones must be represented with signage
14. Which of the following is true of gad retention? Select all that apply.
a. Seen in bone and brain tissue
b. Seen in renal compromised patients
