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 the object are equal to the force of gravity. Lower deflection angles mean the force of
gravity is stronger than the translational force and higher deflection angles indicate that the translational
force is greater.Since we are experiencing 1 gravity force at rest. A deflection of 45 degrees indicates the
translation force is equal to 1G.
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|Page
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 nystagmus?
1. Involuntary coughing and sneezing
2. Vision loss
3. Experience different scents that are not really there
4. Involuntary movement of the eyes from side to side - ANSWER-4. Involuntary movement of the eyes
from side to side
Which of the following contributes to patient heating? Select all that apply.
1. Pulse sequence
2. Body size
3. Surface area
4. All of the above - ANSWER-All of the above
What is the risk associated with translational force?
1. Peripheral nerve stimulation
2. Missile effect
3. Antenna effect
4. Proximity heating - ANSWER-2. Missile effect
An object that produces a weak attractive force in the presence of a strong magnetic field is called what?
