Which gradient is used to alter the magnetic field strength and thus precessional
frequency to select sagittal slices?
a) z-gradient
b) x-gradient
c) y-gradient
d) none of the above
Give this one a try later!
c) y-gradient
Increasing the field of view (FOV) would have what effect?
A. Increase SNR
B. Increase resolution
C. Increase scan time
D. Increase T1 weighting
,Give this one a try later!
A. Increase SNR-Increasing FOV leads to larger pixel size, resulting in more
signal.
A factor that governs the efficiency of the passage of current is the inherent
resistance of the coil. Which law is used to determine the degree of resistance along
a wire?
a) Faraday's law
b) Tesla's law
c) Ohm's law
d) Helmholtz's law
Give this one a try later!
c) Ohm's law
What does MRCP stand for?
A. Magnetic Resonance Choice Preferred

MR conditional means an object is what?
a) demonstrated to pose no known hazards in a specified MRI environment with no
, specified conditions of use
b) demonstrated to pose known hazards in a specified MRI environment with
specified conditions of use
c) demonstrated to pose no known hazards in a specified MRI environment with
specified conditions of use
d) safe to enter the scan room with no research or trepidation in regards to its safety
Give this one a try later!
c) demonstrated to pose no known hazards in a specified MRI environment
with specified conditions of use
A consequence of maximizing resolution using an increase image matrix (FOV) is:
