1. A conservative approach to breast feeding after a mother receives gad
contrast is:
a. To wait 12-24 hours to breastfeed after an IV injection of gad
b. To pump and dump breastmilk for 48 hours after an IV injection of
gad
c. To continue breastfeeding immediately after receiving an IV injection
of gad
d. To mix formula with breastmilk for 24 hours after an IV injection of
gad contrast - correct answer - a. To wait 12-24 hours to breastfeed
after an IV injection of gad
2. When handling a code in the MR environment, which of the following are
NOT best practices?
a. all the choices should not be done
b. Patient should be stable prior to removing from Zone IV
c. Patient must be removed from Zone IV before calling a code
d. It is suggested that a patient be brought to Zone II, but can be in
Zone III if necessary to resuscitate the patient - correct answer - b.
Patient must be stable prior to removing from Zone IV

3. Which of the following are guidelines that can be used for scanning
pacemakers on non-pacemaker dependent patients?
a. A cardiologist or electrophysiologist with ACLS training must be
present for the entire exam
b. Pretest pacemaker function outside the MR environment
c. Constant communication with the patient should take place.
d. An electrophysiologist should test the device during acquisition. -
correct answer - a, b, c
4. Which of the following are a result of the static magnetic field? Select all
that apply.
a. Implants that have ferrous components can cause harm to patients in
its presence
b. Translational force and rotational force can occur with ferrous objects
in its presence
c. Cobalt can demonstrate the missile effect in its presence
d. Patients are exposed to time-varying magnetic fields in its presence. -
correct answer - a, b
The time-varying magnetic field is produced by the gradient coils & RF
transmitter. Ferrous objects can demonstrate rotational and translational
forces.
Cobalt is non-ferrous.
5. The ICNIRP states that moving through a field strength above
_________ may be high enough to produce vertigo and other sensory
perceptions like nausea and magnetophosphenes.
a. 2 T
b. 3 T
c. 4 T
d. 1 T - correct answer - a. 2 T

6. Which of the following agents is the most stable?
a. All are equally stable
b. Non-ionic linear
c. Macrocyclic
d. Ionic linear - correct answer - c. Macrocyclic
(Cages in the gad so it cannot leave the ligand)
7. Which of the following are true of scanning at 3T?
a. Increased chance for burns from implants
b. Different SAR limits than 1.5 T
c. More RF energy deposition in tissue than 1.5 T
d. Less chance for burns from implants - correct answer - c. More RF
energy deposition in tissue than 1.5T
8. All linear agents have demonstrated the same amount of gad retention.
a. True
b. False - correct answer - b. False
9. All of the following are incorrect when using a metal detector for
screening a patient for MR threats except:
a. They are a must in ensuring the safety of our patients
b. They can detect objects that will not produce a threat in the MR
environment
c. They will only detect ferrous objects
, Page |4
d. They are one of the most effective means of identifying risk in MR -
correct answer - b. They can detect objects that will not produce a
threat in the MR environment
10. Tissue heating depends on which of the following factors? Select all
that apply.
a. Tissue conductivity
b. Field strength
c. Tissue permeability
d. Dielectric constant - correct answer - a, b, c, d
11. Why is asphyxia a risk associated with a quench malfunction?
a. Temperature gets so cold that the diaphragm contracts
b. Helium is flammable, so if ignited, it can burn breathable air
c. Air is displaced by expanding helium gas
d. The changing magnetic field associated with a quench that induces
the diaphragm to contract - correct answer - c. Air is displaced by
expanding helium gas
12. Which of the following agents yield the best chance for
transmetallization to occur?
a. Macrocyclic non-ionic
b. Macrocyclic ionic
c. Linear ionic
d. Linear non-ionic - correct answer - d. Linear non-ionic
13. Offers a very weak bond between the gad ion and the ligand. This
makes it susceptible to transmetallization.
