Which of the following are mechanisms for heat dissipation in
patients? Select all that apply.
1. Evaporation
2. Convection
3. Radiation
4. Conduction - ANSWER-1. Evaporation
2. Convection
3. Radiation
4. Conduction
All of the choices are mechanisms for heat dissipation.
An example of convection is a fan blowing over our patients to
cool them.
, Page |2
An example of evaporation is the patient sweating to cool them.
An example of conduction is placing an ice pack on our patient.
An example of radiation is the patient emitting heat.
During acquisition, it is noticed that the T wave of the cardiac
cycle is elevated. What is this artifact called?
1. Magnetophosphenes
2. Magnetohydrodynamic effect
3. Teratogenesis
4. Excitation - ANSWER-2. Magnetohydrodynamic effect
How is active shielding accomplished?
1. A magnetically conductive material surrounds the MR unit and
this shapes and contains the magnetic field
2. Bricks of permanent magnets are stacked around the MR unit
to contain the fringe field
, Page |3
3. A coil of wire in the MR unit has a current running through it
which produces a magnetic field opposing the B0
4. Nothing is used with active shielding - ANSWER-3. A coil of
wire in the MR unit has a current running through it which
produces a magnetic field opposing the B0
A coil of wire is used with a current of wire running through it to
produce a magnetic field. Wires are oriented to produce a
magnetic field opposing the vector of the static magnetic field,
canceling out some of the magnetic fields forced felt outside of
the gantry.
The electric fields associated with RF cause what?
1. Rotational force
2. Translational force
3. Heat deposition
4. Peripheral nerve stimulation - ANSWER-3. Heat deposition
, Page |4
Which of the following is a short-term effect of gadolinium
contrast?
1. Gadolinium retention
2. GAP
3. Nausea
4. NSF - ANSWER-3. Nausea
As blood flows through a vessel, currents can be induced in an
MR field. What is this called?
1. Translational forces
2. Magnetophosphenes
3. Flow potential
4. Fringe field - ANSWER-3. Flow potential
What is the ICNIRP occupational exposure limit for exposure of
the head and trunk to static magnetic fields?
