effect will this have on the # of slices available? - ANSWERS-
Decrease
Fast spin echo technique will have a lower SNR compared to
conventional spin echo techniques. true or false? -
ANSWERS-True
In a T2 weighted FSE image, fat will appear how when
compared to a conventional SE sequence? - ANSWERS-
Bright
,Which of the following ETL would the operator select in
order to acquire the maximum T2 weighting during a FSE? -
ANSWERS-ETL of 16
The start up cost for a superconductive magnet is high. true
or false? - ANSWERS-true ; Initial cost may exceed two
million dollars in addition to the expensive cyrogen up keep.
A type of magnet that is generally used for a 1.0t or a 1.5t
system is a: - ANSWERS-Superconductive magnet
The basic type of magnets used in MR are: - ANSWERS-
Permanent, resistive , superconductive
A procedure called shimming: - ANSWERS-Adjust the
magnetic field to achieve the most homogenous field
Superconductive magnets utilize two types of cyrogens. -
ANSWERS-Helium and nitrogen
Types of transmit coils are: - ANSWERS-a) Body, b) head, c)
volume coils, d) all of the above. D all of the above
,Various types of receiver coils are: - ANSWERS-a) solenoidal
coil, b) volume,birdcage,surface coil, c) Helmholtz pair coil,
d) All of the above: D all of the coils are true receiver coils
To gain SNR and gain high resolution: - ANSWERS-Use a
small surface coil
Which of the following is not an example of a surface coil: -
ANSWERS-body coils are not surface coils
In a cross-sectional view of the magnet bore, which set of
coils are the closest to the bore? - ANSWERS-RF coil- the
cross sectional of the MR system reveals the order of
thecoils: the magnet bore, then the RF coils, Then the
gradient coils, then the shim coils & the outer most are
magnet coils.
MR systems can be shielded by two processes. They are: -
ANSWERS-Passive and active shielding
The more expensive type of shielding that uses additional
solenoid magnets outside the cyrogen bath that restricts the
magnetic field line to an acceptable location is the: -
ANSWERS-Active- passive shielding can be accomplished by
, lining the walls with steel while the more expensive
alternative is active shielding
The exact middle of the bore of the magnet is termed: -
ANSWERS-Isocenter
Without proper safety limits on the MR system exposure to
the time-varying magnetic fields created by the rapid
switching of the gradient could create a potential
environment for: - ANSWERS-Including electrical current in
the patient's tissues
Faraday's Law deals with induction of a current by a
magnet. true or false? - ANSWERS-true
The orientation of the main magnetic field of a low field
permanent magnet is vertical. True or false? - ANSWERS-
True ; permanent lowfield magnets utilize a magnetic field
oriented vertically
Superconductive magnets have high homogeneity compared
to other magnets types. true or false? - ANSWERS-true ; One
advantage of a superconductive magnet is its excellent
homogeneity
