MRSO Exam Question and Answer 2026 |
Practice Questions and Comprehensive
Solutions | Grade A+
• Gad contrast has been found in the body in what form? Select all that
apply.
a. Water-soluble
b. Non-water soluble -✓✓a, b
• Which of the following would we expect to be the loudest sequence?
a. GRASS
b. Fast spin echo
c. Conventional gradient sequence
d. FLAIR -✓✓a. GRASS
The FLAIR and fast spin echo are considered spin echo sequences; they
do not have extremely fast changing gradient, so will not produce as
much noise.
• Which of the following has a steeper spatial magnetic gradient?
a. Vertical B0
b. Horizontal B0 -✓✓a. Vertical B0
• The strongest gradient strength will reach maximum strength how far
from isocenter?
,a. 5-20 cm
b. 20-40 cm
c. 30-60 cm
d. 5-15 cm -✓✓c. 30-60 cm
• Which of the following is true of gad and breastfeeding mothers?
Select all that apply.
a. Gad is found in breast milk in a stable and chelated form
b. It is thought that gad contrast may alter the taste of breastmilk.
c. Available data suggests that breastmilk should be pumped and
discarded for 24 hours after the IV dose
d. 20% of the intravascular dose would be excreted into the breastmilk
within the first 24 hours. -✓✓a, b
• Which of the following will influence peripheral nerve stimulation?
a. Static magnetic field
b. Magnetic field at isocenter
c. Patient weight
d. Slew rate -✓✓d. Slew rate
• Which of the following pulse sequences would we expect to see the
least patient heating?
, a. Incoherent gradient
b. STIR
c. Fast spin echo
d. EPI -✓✓d. EPI
• A patient comes in with a 1 cm brain aneurysm clip and you find the
package which lists what metal it is made from. Which of the following
metals would make it unsafe to scan this patient?
a. Elgiloy
b. Phynox
c. MP35N
d. 405 Stainless steel -✓✓d. 405 Stainless steel
Phynox, elgiloy, titanium, and 316 stainless steel are non-ferrous.
17-7PH and 405 stainless steel are ferrous
• Which of the following are true of Lenz's force?
a. Occurs because of the interaction between a ferrous object and the
static magnetic field
b. Influences objects that are electrically conductive
c. Influence on an object depends on the field strength
