An artificial object that can be imaged to test the performance and quality of a
magnetic resonance system would be:
A. Lead cutting block
B. A gradient
,C. Vit E capsule
D. Phantom

___________ is defined as the Z component of the net magnetization vector in the
direction of the static magnetic field.
A. Presaturation
B. Longitudinal magnetization
C. Transverse magnetization
D. Free induction decay (FID)
E. Transverse gradient

B. Longitudinal magnetization
Longitudinal magnetization - The Z component of the net magnetization
vector in the direction of the static magnetic field. Following RF excitation,
this vector returns to its equilibrium value at a rate characterized by the
time constant T1.
A ___________ is an instrument (or document) that allows a patient to appoint an agent to
make health care decisions in the event that the primary individual is incapable of
executing such decisions.
A. Tort doctrine
B. Standard of care
C. Respondeat superior
D. Health care proxy

, D. Health care proxy
What is the term for the echo generated by switching a pair of dephasing and
rephasing gradients, without the use of a 180° refocusing pulse?
A. Inversion echo
B. Cavernous echo
C. Gradient echo
D. Reciprocal echo

C. Gradient echo
The timing the collection of MR data to physiological motion in order to minimize
motion artifacts is known as:
A. Synchronization
B. Fourier transformation
C. Carbonation
D. Gating

D. Gating
A ___________ is a medical or psychological treatment guideline, and can be general or
specific.
A. Explanation of benefits
B. Standard of care
C. WebMD symptom checker
, D. Tort doctrine
E. Nosocomial plan

_______________ occurs when slices are positioned too close together, causing signals from
adjacent slices to affect one another.
A. Chemical shift
B. Aliasing artifact
C. Cross talk artifact
D. Ghosting
Give this one a try later!
C. Cross talk artifact
Cross-talk artifact occurs when slices are positioned too close together,
causing signals from adjacent slices to affect one another. This affects T1
contrast, and is remedied by utilizing an interleaved slice profile.
________ is defined as a patient's permission to a medical or surgical procedure or to
participation in a clinical study after being properly advised of the relevant medical
facts and the risks involved.
A. Res Ipsa Loquitur
B. Implied consent
C. Informed consent
D. Statutory law
