MRI ACCREDATION PRACTICE EXAM WITH COMPLETE 250
QUESTIONS AND CORRECT DETAILED ANSWERS |ALREADY
GRADED A+(Newest Version 2025/2026)
What is a superconducting magnet?-ANSWER-Wire that is
coiled or winded which allows a current to pass through
creating a magnetic field of 1.5–3 tesla.
What is the magnetic field strength of 1.5T?-ANSWER-63.9MHz
Why is liquid helium used?-ANSWER-In order to maintain a
large energy, there needs to be 0 resistance. This is achieved
by the wire being bathed in the helium at –452.4 degrees.
, What is the a disadvantage of helium ?-ANSWER-Very
expensive but the high field strengths allow for the highest
imaging quality.
How is interference to the MF kept to a minimum?-ANSWER-
The faraday cage is used to prevent external RF signals from
being added to the data collected. This surrounds the room to
prevent interruptions from entering.
What is TE?-ANSWER-Echo time: the time in milliseconds
between the application go the 90 degree pulse and the peak
of the echo signal.
What is TR?-ANSWER-The reputation time defined as the time
between successive pulse sequences applied to the same slice.
What is precession?-ANSWER-It is when the protons spin on
their axis. The rate of precession is called the lam our
frequency.
What is significant about the lam our frequency ?-ANSWER-The
frequency changes are proportional to the magnetic field
strength. (Faster precession at higher energies). This means it
