Maintaining an ambient room temperature between 65-75 degrees F, a relative
humidity of 50-70%, and adequate air flow in the MR imaging room is recommended
to: - CoRReCt anSweR-make patients more tolerant of the radio frequency heating
effects
The FDA defines the specific absorption rate to be below the level of concern at: -
CoRReCt anSweR-less than or equal to 4 W/kg averaged over the body
If the parameters selected for an imaging sequence will expose the patient to
specific absorption rate levels in excess of the FDA defined level of no concern, they
should never be employed on patients who are: - CoRReCt anSweR-febrile
The FDA safe level for exposure to radio frequency radiation during an MR procedure
is defined by restricting the specific absorption rate levels. Specific absorption rate
level restrictions are imposed to control the risk of: - CoRReCt anSweR-systemic and /
or local thermal injury
Studies have demonstrated that persons with suspected intraocular metallic bodies
must be screened prior to entering the static magnetic field. This can be adequately
accomplished by obtaining: - CoRReCt anSweR-plain film x-rays of the orbits
Orbital screening for suspected intraocular metallic bodies should be done prior to
admitting patients and personnel into an MR system: - CoRReCt anSweR-at or above
0.01 Tesla strength
, Patients with tattooed eyeliner and / or eye makeup containing ferrous pigment
should be screened and advised of what possible complication of MR imaging? -
CoRReCt anSweR-transient skin irritation or cutaneous swelling of the eyes and
surrounding tissues
Pregnant MR technologists should be restricted from entry into the electromagnetic
fields of the MR scanner. (True or False) - CoRReCt anSweR-false
The FDA defines the specific absorption rate to be at the level of concern when
exposure to the radio frequency energy produces a core temperature increase in the
body of: - CoRReCt anSweR-1.0 degree C
Acceptable safe levels for exposure of persons with cardiac pacemakers and
defibrillators to magnetic fields should be enforced at the ________ gauss perimeter in
the magnetic fringe field. - CoRReCt anSweR-5.0
Patients with Swanz Ganz catheters should not undergo MR procedures because: -
CoRReCt anSweR-eddy current inductive heating may melt the catheter
What technique change could be employed to reduce radio frequency power
deposition and circumvent the specific absorption rate limitations? - CoRReCt
anSweR-shoulder
Specific absorption rate limitation problems are more likely to be experienced using
which transmitter coil: - CoRReCt anSweR-body
If electronic decoupling of the coils is not available on an MR system, the position of
the receiver coil to the transmitter must be true to an orthogonal plane (usually
horizontal) of the magnet to avoid: - CoRReCt anSweR-possible damage to the coil
