MRI FINAL QUESTIONS WITH COMPLETE
SOLUTIONS
A pulse sequence that uses a variable flip angle followed by
gradient rephasing is known as: Correct Answers gradient echo
A sagittal image of the brain should include: Correct Answers
from the foramen magnum to the top of the head
A spin echo (SE) exam is identified by its use of: Correct
Answers a 90 degree excitation pulse followed by one or more
180 degree refocusing pulses
A STIR pulse sequence is useful because it reduces or eliminates
signal from: Correct Answers fat
According to the authors of your textbook, when scanning the
shoulder, the hand should be positioned so that the: Correct
Answers thumb is pointing up (neutral position)
According to the text, negative contrast agents are most often
used to image: Correct Answers abdomen
All head exams typically find the patient positioned: Correct
Answers supine, head first, with the head in the head coil
An artifact seen as anatomy 'wrapping' from another location is
known as: Correct Answers aliasing
An axial image, that demonstrates a bright or hyperintense
bladder, is mostly likely what Correct Answers T2 weighted
,Applying a 90 degree RF pulse to selected tissue before a pulse
sequence begins is an example of: Correct Answers spatial
presaturation
As TR is decreased: Correct Answers available slices per
acquisition are decreased
Attaching a photo sensor to a finger or toe to detect the increase
in blood volume in the capillary bed during systole is known as:
Correct Answers peripheral gating
Axial scans of the elbow are typically acquired: Correct
Answers with an oblique angle, with the medial edge more
inferior than the lateral edge
Axial slices of the hip are prescribed from: Correct Answers
above the acetabulum to the superior edge of the lesser
trochanter
Axial slices of the liver should be prescribed: Correct Answers
from the inferior margin of the liver to the diaphragm
Axial slices should be aligned: Correct Answers parallel to the
anterior-posterior commissure axis
B-values are associated with what type of scan? Correct
Answers diffusion weighted imaging (DWI)
, Based on the images found in your text, a sagittal T2 weighted
image shows CSF to be: Correct Answers hyperintense to the
spinal cord (bright)
Based on the images found in your textbook, CSF on a T1
weighted image appears: Correct Answers hypointense to the
spinal cord (dark)
Cardiac gating requires a modification of the normal TR period.
The TR period during cardiac gating is measured by the:
Correct Answers R wave to R wave interval
Cardiac gating uses cardiac leads to ensure that the MRI signal
is obtained: Correct Answers at the same phase of the cardiac
cycle
Common indications for scanning of the male pelvis include all
of the following EXCEPT: Correct Answers cervical lesions
Coronal and sagittal slices of the thoracic spine should include
anatomy from: Correct Answers C7 through the conus
Coronal slices of the shoulder should be prescribed from the:
Correct Answers infraspinatus posteriorly to the subscapularis
anteriorly
Correct positioning of the respiratory bellows should be:
Correct Answers at an angle to catch both thoracic and
abdominal movements during respiration
