MRSO SAFETY EXAM 2024-2025


Slew rate - Answer The speed with which the gradient coil turns on and off

Time-varying Gradient - Answer: Induced current in a patient


ANSWER: Magnetic flux lines travel from the north to the south pole.


ANSWER: Permanent Magnet Cannot be turned off.

Very affordable; and incredibly heavy.

Around 0.4T.

Vertical vector.


ANSWER: A resistive magnet Can switch on and off.

Costly because of cooling.

Around 0.6T.

Vertical or horizontal vector?


Superconductive magnet - Approximately 10T.

Low electricity; fair cost.


Active shielding - ANSWER To diminish the fringe field, a wire coil with an
electrical current running through it is used to generate an electromagnetic field
that opposes the static magnetic field.

, B-sub zero - ANSWER The unit used to describe static magnetic fields


Deflection - Answer The degree of attraction an object has to the static magnetic
field.


Diamagnetism - Answer A weakly repelling force when put in a strong static
magnetic field.


Faraday's Law of Induction: ANSWER This outlines how electrical currents are
generated in the presence of an alternating magnetic field.


Ferromagnetism - Answer An item with significant attraction force, in a strong
static magnetic field, that retains a magnetic field even after leaving the strong
static magnetic field.


Fringe field - Answer The magnetic field that extends beyond of the MRI unit


Gauss - Answer A magnetic field unit of measurement.


Lenz's Force - ANSWER When nonferrous items move through a strong static
magnetic field, they produce a magnetic field.


Magnetic moment - ANSWER Each hydrogen proton produces its magnetic field.


Magnetohydrodynamic Effect - Answer When a patient is subjected to a powerful
static magnetic field, their blood gets magnetized. This results in an increased T
wave in the cardiac cycle.


Paramagnetic - Answer A weakly attracting force when placed in a static magnetic
field.
