Question 1
Which term best describes the magnetic field strength at the
center of an MR scanner?
a) Gradient field
b) Radiofrequency field
c) Static magnetic field (B₀)
d) Eddy current field
Answer: c
2
,Rationale: The static magnetic field, denoted B₀, is the uniform,
high-strength field generated by the main magnet and is present
continuously during scanning . This is the primary field that aligns
hydrogen protons and is measured in Tesla (T) or Gauss (G).
Question 2
What is the conversion between Tesla and Gauss?
a) 1 T = 100 G
b) 1 T = 1,000 G
c) 1 T = 10,000 G
d) 1 T = 100,000 G
Answer: c
Rationale: 1 Tesla equals 10,000 Gauss. This conversion is essential
for understanding magnetic field strength measurements, as the 5
Gauss line is a critical safety boundary .
3
, Question 3
The Larmor equation is expressed as:
a) ω = γ × B₀
b) B = μ(H + M)
c) F = mg × tan(α)
d) SAR = (RF power)/mass
Answer: a
*Rationale: The Larmor equation (ω = γ × B₀) describes the
precessional frequency of hydrogen protons, where ω is
frequency in Hz, γ is the gyromagnetic ratio (42.58 MHz/T for
hydrogen), and B₀ is the static magnetic field strength .*
Question 4
What is the resonance frequency at 1.5 Tesla?
