MRSO – 2 EXAM (ACTUAL EXAM) 65QUESTIONS WITH VERY ELABORATED
ANSWERS CORRECTRY
Which of the following produce the greatest chance for peripheral nerve
stimulation?
a. Conventional spin echo
b. Fast spin echo
c. Gradient echo
d. EPI - d. EPI
A deflection of 45 degrees in a tested implant indicates that it deflects at a force
equal to what?
a. 0.5 gravity force
b. 2 gravity force
c. 0.25 gravity force
d. 1 gravity force - d. 1 gravity force
4T/m is equal to what?
a. 4000 G/cm
b. 4G/cm
c. 40 G/cm
d. 400 G/cm - d. 400 G/cm
1T = 10,000 G
1m = 100 cm
Therefore, 1 T/m=10,000G/100cm
This means that 1 T/m=100 G/cm
How do we calculate the maximal spatial gradient?
a. dB/dx * B
b. dB/dt * W/kg
c. W/kg
, d. B - a. dB/dx * B

a. Less than blood
b. Greater than blood
c. Less than water
d. Equal to blood - b. Greater than blood (and greater than water)
Which of the following is true if we increase the field of view from 200mm to
400mm?
a. We reduce patient heating
b. We use a stronger time-varying gradient magnetic field
c. We use a weak time-varying gradient magnetic field
d. We increase the patient heating - c. We use a weak time-varying magnetic field.
Larger field of views will produce lower resolution exams. The size of the field of
view is dependent on the frequency encoding gradient coil. When we increase the
field of view, we decrease the amplitude of our gradient coil.
When a T1 weighted image is taken of a vial of gad contrast, it will appear how?
a. Bright
b. Dark
c. Gray
d. Blue - b. Dark
Active shield is performed how?
a. Nothing is used with active shielding
b. A magnetically conductive material surrounds the MR unit and this shapes and
contains the magnetic field
