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

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
d. EPA - ANSWER-a. ACR Blue Ribbon Panel on MR safety
Which of the following is true of a gad contrast osmolarity?
a. Less than blood
b. Greater than blood
c. Less than water
d. Equal to blood - ANSWER-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?
2|Page
, MRSO EXAM 2 MAGNETIC RESONANCE SAFETY OFFICER EXAM
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 - ANSWER-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 - ANSWER-b. Dark
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
