Which of the following best describes an IR sequence?
A. A 180° pulse followed by a 90°/180° combination
B. A 90° pulse followed by a 180° pulse
C. A train of gradient echoes
D. A train of spin echoes
A 180° pulse followed by a 90°/180° combination
Gradient echo sequences requiring high signal from fluid are known as all of the following
EXCEPT:
A. T2* gradient echo
B. Steady-state gradient echo

Incoherent gradient echo
The medial and lateral rectus muscles are located in the:
A. Ears
B. Posterior pelvic region
C. Proximal calves
D. Eyes
E. Superior shoulder regions
F. Soft tissues of the neck
Eyes
Reducing the number of lines filled in k-space will produce an image:
A. With a decrease in spatial resolution
B. With a increase in spatial resolution
C. With an decrease in overall SNR
D. With an increase in overall SNR
E. With a reduced overall scan time
F. B, C and E only
G. A, D and E only
A, D and E only
Page 2 of 98
,Reducing the number of lines filled in k-space reduces the number of phase encoding steps,
resulting in shorter scan time, an increase in overall SNR, but a decrease in spatial resolution.

matrix is _________ mm.
A. 0.76mm

D. 1.13mm
E. 1.24mm
0.88mm

A. Emitted from
B. Attenuated by
C. Amplified from
D. Reflected off

precautions should be used for HIV-positive patients in the MRI suite?
A. Respiratory
B. Droplet
C. Standard (universal)
D. Enteric
E. Contact

C. Inferior to slice group
D. Superior to slice group
Superior to slice group
Which of the following best describes an EPI sequence?
A. A 180° pulse followed by a 90°/180° combination
B. A 90° pulse followed by a 180° pulse
C. A train of gradient echoes
