What is the name of the gradient coil
used to produce sagittal and coronal im-
ages?
a. Transverse coil b. Golay coil ("saddle coil")
b. Golay coil
c. Maxwell coil
d. Receiver coil
Which of the following is able to handle
the most RF heating?
a. elderly d. neonate
b. adult
c. obese adult
d. neonate
Which of the following techniques can
be used to increase the echo spacing?
b, e
Select all that apply.
Decreasing the receiving bandwidth will
a. Increase the TR
be lengthening the sample time. This
b. Decrease receiving bandwidth
may force us to increase our TE as well
c. Increase receiving bandwidth
as the TR. Increasing the field of view will
d. Use a receive only coil
also allow for longer echo spacing.
e. Increase field of view
f. Increase flip angle
The differences in magnetic field
strength as you approach the MRI unit is
termed what?
a. Spatial magnetic gradient
a. Spatial magnetic gradient Measured in dB/dx
b. Gauss line
c. RF energy
d. Gradient coils
Which of the following produce the great-
est chance for peripheral nerve stimula-
d. EPI
tion?
, a. Conventional spin echo
b. Fast spin echo
c. Gradient echo
d. EPI
A deflection of 45 degrees in a tested
implant indicates that it deflects at a force
equal to what?
d.1 gravity force
a. 0.5 gravity force
b. 2 gravity force
c. 0.25 gravity force
d. 1 gravity force
4T/m is equal to what?
d. 400 G/cm
1T = 10,000 G
a. 4000 G/cm
1m = 100 cm
b. 4G/cm
Therefore, 1 T/m=10,000G/100cm
c. 40 G/cm
This means that 1 T/m=100 G/cm
d. 400 G/cm

b. FDA
c. OSHA
d. EPA
Which of the following is true of a gad
contrast osmolarity? b. Greater than blood (and greater than
water)
a. Less than blood
