1. When imaging a geriatric patient, while performing a PCA MRA sequence, what
imaging parameter might the operator adjust?
A. Field of view
B. Presaturation band location
C. Slice thickness
D. VENC
E. Contrast injection rate
Correct Answer: D. VENC
Rationale: VENC (Velocity Encoding) is adjusted in MRA sequences to match the
expected blood flow velocities, especially important in older patients who may have
vascular disease affecting flow dynamics.
2. As the number of phase encodings is increased from 256 to 512, SNR (signal to
noise ratio):
A. Increases
B. Decreases
C. Doubles
D. Does not change
E. Quadruples
Correct Answer: B. Decreases
Rationale: Increasing phase encodings leads to smaller voxel size, which reduces SNR
since less signal is captured per voxel.
3. A magnetic vector possesses attributes of both __________ and _____________.
A. Strength; magnitude
B. Direction; purpose
C. Strength; flow
D. Magnitude; direction
Correct Answer: D. Magnitude; direction
Rationale: A vector in physics, including a magnetic vector, is defined by both its
magnitude (strength) and direction.
4. What element in the body is the principal nucleus utilized in clinical MR imaging?
A. Helium
B. Hydrogen
C. Oxygen
D. Calcium
Correct Answer: B. Hydrogen
Rationale: Hydrogen is abundant in the human body and has a single proton, making it
ideal for MRI signal generation.
