Console area, MRI staff and screened patients only. → Zone 3,
General public access, outside the MRI Department. → Zone 1,
Scan room itself. Where the actual MRI scanner is. → Zone 4,
Interface between public space and the MRI Department. Typically reception desk /
registration. → Zone 2 - CORRECT ANSWER --
Sensitivity in diagnostic imaging means the images are able to detect pathology. -
CORRECT ANSWER --true
Which parameter controls whether an IR sequence will be a STIR or a FLAIR? -
CORRECT ANSWER --ti tau
Sequence that does not use a 180 degree refocusing pulse → GRE,
Sequence that resurrects the FID using a 180 degree RF pulse but is generally slow
→ CSE,
Sequence that has a parameter known as Tau → IR,
Sequence that has a parameter known as ETS → TSE - CORRECT ANSWER --

- CORRECT ANSWER --false
are medical doctors who diagnose and treat mental, emotional, and behavioral
disorders. - CORRECT ANSWER --Psychiatrists
Incident Reports only need to be filed if an actual injury occurred. - CORRECT
ANSWER --false
Titanium Orthopedic Hardware is extremely dangerous to scan. - CORRECT
ANSWER --false
Sequence that is sometimes described as a 'virtual biopsy' → MRS,
Sequence that has an advantage when assessing for labral tear → MR
Arthrography,
Blood vessel visualization technique that uses the phase shift between moving and
stationary spins → PC MRA,
Sequence sensitive for ischemic stroke → DWI,
Sequence that utilizes difference in signal between stationary spins and spins
moving perpendicular to the slice → TOF MRA,
Sequence that aims to tell which regions of the brain are active during an activity →
fMRI - CORRECT ANSWER --
What sequence produces Black Blood MRA images? - CORRECT ANSWER --Spin
Echo TOF
, If NSA is changed from "1" to "4", the scan time is then multiplied by: - CORRECT
ANSWER --4
What does the transmit attenuation adjust to generate the appropriate B1 magnetic
field? - CORRECT ANSWER --Voltage and current
Which of the following is a Physicist/ MR Scientist's annual QC test? - CORRECT

Thickness
The safest way to lift something heavy is to mainly use the muscles of your ____ and
____ and to keep your back as ____ as possible. - CORRECT ANSWER --arms legs
straight
It can fill multiple rows of K-space (e.g. 6) per TR, thus reducing scan time → FSE, It
can void signal from fluid → FLAIR, Used to freeze motion (e.g. fetal imaging) →
SSFSE, It can void signal from fat → STIR, It can produce PD and T2 weighted
image at the same time → Double Echo Spin Echo - CORRECT ANSWER --
TR is set at 800 ms and the maximum number of slices per acquisition is 8. If the
technologist has prescribed 25 slices, how many acquisitions (concatenations) would
be required for the sequence? - CORRECT ANSWER --4
Gadolinium is used as contrast material because it is a ____________ material. -
CORRECT ANSWER --Paramagnetic
Which of these is an advantage of GRE? - CORRECT ANSWER --Generally Faster
In SE, the echo/signal is obtained by the rephasing of the spins through the use of
a/n ____ - CORRECT ANSWER --The correct answer is: 180 RF
rephasing/refocusing pulse
If TR is 400 ms and the maximum number of slices per TR is 6, how many
concatenations are needed to acquire 26 slices assuming you cannot change the
TR? - CORRECT ANSWER --5
The correct answer is: T1 image contrast → dark fluid bright fat, PD image contrast
→ fluid a little brighter than fat (little contrast), T2 image contrast → dark fat bright
fluid - CORRECT ANSWER --
One of the advantages of a SE sequence, even if its scan time is longer than a GRE
sequence due to the presence of the 180RF pulse, is that is can provide true T2
weighted images thanks to the 180 RF refocusing/rephasing pulse. - CORRECT
ANSWER --true
