SECTION 1: MRI PHYSICS & FUNDAMENTALS
(Questions 1-30)
,Question 1
Originally, Magnetic Resonance Imaging was known by which name?
A) Magnetic Resonance Angiography
B) Magnetic Relaxation Imaging
C) Nuclear Magnetic Resonance
D) Nuclear Resonance Imaging
Correct Answer: C
Rationale: MRI was originally known as Nuclear Magnetic Resonance (NMR). The
term "nuclear" was dropped to alleviate public concern about radiation, though
the physics behind the imaging modality remains unchanged.
Question 2
In MRI, substances respond to a specific radio frequency which is known as:
A) Magnetic frequency
B) Radio frequency
C) Gyro-magnetic frequency
D) Resonance frequency
Correct Answer: D
Rationale: Each substance has a specific resonance frequency at which it
absorbs and re-emits RF energy. This is known as the resonance frequency or
Larmor frequency.
Question 3
What are the three components necessary for MRI on a very basic level?
A) Magnetic, nuclei, radiowave
B) Magnetic, electrons, radiowave
C) Electric, nuclei, radiowave
D) Magnetic, protons, laser
,Correct Answer: A
Rationale: The three fundamental components required for MRI are: (1) a strong
magnetic field, (2) nuclei with a magnetic moment (such as hydrogen protons),
and (3) radiofrequency waves to excite the nuclei.
Question 4
Magnetic fields have strength and direction, which are represented by a:
A) Scalar
B) Vector
C) Tensor
D) Dipole
Correct Answer: B
Rationale: A vector is a quantity that has both magnitude (strength) and
direction. Magnetic fields are represented by vectors in MRI physics.
Question 5
When symbolizing the flow and area of a magnetic field, special lines are used,
called:
A) Field or flux lines
B) Isointense lines
C) Gradient lines
D) Vector lines
Correct Answer: A
Rationale: Magnetic field lines, also called flux lines, visually represent the
direction and strength of a magnetic field. They flow from the north pole to the
south pole outside the magnet.
, Question 6
The magnetic field of any magnet has a direction, signified north and south. This
property of a magnet makes it a:
A) Monopole
B) Dipole
C) Quadrupole
D) Multipole
Correct Answer: B
Rationale: A dipole has two poles: a north pole and a south pole. All magnets are
dipoles, and this property is fundamental to MRI physics.
Question 7
The law: "In a loop of conductor where an electric current is introduced and
maintained, a magnetic field will be produced in the center" is attributed to:
A) Faraday
B) Lenz
C) Maxwell
D) Ampère
Correct Answer: A
Rationale: Michael Faraday discovered electromagnetic induction,
demonstrating that a magnetic field is produced around a conductor carrying an
electric current. This principle is fundamental to the construction of MRI
magnets.
Question 8
When describing the strength of an MRI main magnetic field, the SI unit most
commonly used is:
A) Gauss
B) Tesla
