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
,2|Page
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
,3|Page
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
, 4|Page
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
