Which of the following are considered biological effects of
the static magnetic field?
1. Rotational forces
2. Magnetohydrodynamic effect
3. All of the choices
4. Translational forces - ANSWER-2.
Magnetohydrodynamic effect
A patient starts twitching during a diffusion-weighted image
but not during any other sequences. When questioned,
they say that they are holding still. What may be
happening?
1. The patient may be experiencing peripheral nerve
stimulation
2. The patient is definitely lying to you
3. The patient has Parkinson's disease
4. Patient has dementia - ANSWER-1. The patient may be
experiencing peripheral nerve stimulation

A patient is advanced through the MRI scanner bore very
quickly and experiences the sensation of flashing lights in
their visual field. What are they experiencing?
1. Heating
2. Magnetohydrodynamic effect
3. Nystagmus
4. Magnetophosphenes - ANSWER-4.
Magnetophosphenes
The magnetohydrodynamic effect explains artifacts seen
where in the cardiac cycle?
1. R wave
2. T wave
3. QRS complex
4. P wave - ANSWER-2. T wave
Due to flow potentials caused by moving blood, artifacts in
ECG can arise and cause an elevation of the T wave of
the cardiac cycle in patients in the static magnetic field.

This causes no harm to a patient and upon leaving the
static magnetic field, the T wave will return to normal.
Heating is common in which of the following? Select all
that apply.
1. The end of an insulated wire
2. In areas outside the RF field
3. In round small objects
4. In devices with sharp points or edges - ANSWER-4. In
devices with sharp points or edges
The T wave in the cardiac cycle represents what?
1. Heart depolarization
2. Arrhythmia
3. Heart repolarization
4. None of the choices - ANSWER-3. Heart repolarization
The QRS complex demonstrates heart contraction
(ventricular depolarization) in the cardiac cycle. The T
wave represents the repolarization of the heart.

What is the purpose of the static magnetic field?
1. To align hydrogen nuclei parallel and anti-parallel to B0
2. To reverse the spin of the hydrogen nuclei
3. To produce currents in tissues containing hydrogen
nuclei
4. To measure the movement of hydrogen nuclei -
ANSWER-1. To align hydrogen nuclei parallel and anti-
parallel to B0
A deflection of 45 degrees in a tested implant indicates
that it deflects at a force equal to what?
1. 2 gravity force
2. 0.25 gravity force
3. 1 gravity force
4. 0.5 gravity force - ANSWER-3. 1 gravity force
Deflection angle describes the magnitude of the
translational magnetic force on an object. If an implant in
the static field is suspended by a string and deflects 45
degrees that means that the translational forces acting on
