GRADED |80 REAL & COMPLETE QUESTIONS AND ANSWERS | 2026
VERSION , GET IT CORRECT!!!
Peripheral nerve stimulation can be described by which of the following?
a. Faraday's law of induction
b. Ohm's law
c. Lenz's law
d. Planks Law - (ANSWER)b. Faraday's law of induction (describes the induction of electrical
current in the presence of a changing magnetic field).
Lenz's force describes the opposing forces created.
Ohm's law deals with the resistance of current along a wire.
Gad contrast has been found in the body in what form? Select all that apply.
a. Water-soluble
b. Non-water soluble - (ANSWER)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 - (ANSWER)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 - (ANSWER)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 - (ANSWER)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. -
(ANSWER)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 - (ANSWER)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
