MRSO GRADED APLUS QUESTION
COLLECTION WITH DETAILED SOLUTION
COVERAGE
●● Which of the following is able to handle the most RF heating?
a. elderly
b. adult
c. obese adult
d. neonate
Answer: d. neonate
●● Which of the following techniques can be used to increase the echo
spacing? Select all that apply.
a. Increase the TR
b. Decrease receiving bandwidth
c. Increase receiving bandwidth
d. Use a receive only coil
e. Increase field of view
f. Increase flip angle
Answer: b, e
,Decreasing the receiving bandwidth will be lengthening the sample time.
This may force us to increase our TE as well as the TR. Increasing the
field of view will also allow for longer echo spacing.
●● The differences in magnetic field strength as you approach the MRI
unit is termed what?
a. Spatial magnetic gradient
b. Gauss line
c. RF energy
d. Gradient coils
Answer: a. Spatial magnetic gradient
Measured in dB/dx
●● 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
Answer: 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
Answer: 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
Answer: 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
