What is the name of the gradient coil used to produce sagittal and
coronal images?
a. Transverse coil
b. Golay coil
c. Maxwell coil
d. Receiver coil - ANSWER-b. Golay coil ("saddle coil")
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
How do we calculate the maximal spatial gradient?
a. dB/dx * B
b. dB/dt * W/kg
c. W/kg
d. B - ANSWER-a. dB/dx * B
What group issued the ACR white paper MRI safety?
a. ACR Blue Ribbon Panel on MR safety
b. FDA
c. OSHA
