MRI safety ARMRIT AND ARRT
The pulse sequence that should be utilized the least in a patient with implanted metallic
hardware is: - answer Gradient echo Gradient echo sequences lack a 180° RF pulse
that aids in correcting local magnetic field inhomogeneities, found in metallic implants.
A patient with a history of _______ should have their GFR checked prior to the
administration of IV contrast. - answer KIDNEY DISEASE, HYPERTENSION,
DIABETES, All of the above
Adequate patient care dictates a patient having an MRI should be __________
monitored. - answer Visually and/or verbally
Patient types who may require additional monitoring while undergoing an MR exam
might include: - answer All of the above
The effect by which a patient may experience a visual stimulation, described as "seeing
stars", is known as: - answer Magneto phosphenes
When moving blood enters a magnetic field, an effect on the ECG seen as a "T wave
swelling" or spike occurs, also known as: - answer Magnetohydrodynamic effect When
moving blood enters a magnetic field, an effect on the ECG seen as a "T wave swelling"
or spike occurs, also known as the magnetohydrodynamic effect, or also known as
magnet-hydrodynamic effect or magnet-hemodynamic effect.
Regions of the body that do not quickly dissipate thermal absorption from SAR during
MR procedures are: - answerEyes and testicles Regions of the body that do not quickly
dissipate thermal absorption from SAR during MR procedures are the eyes and
testicles.
The following items are typically permitted access to enter a high field MRI system
during an MRI guided core biopsy: - answerAluminum interventional equipment AND
Sterile nonferrous biopsy tray C and/or D
Prior to entering the MRI scan room, a patient should be screened for: - answerAll of the
above Prior to entering the MR scan room, patients should be screened for surgical
implants, pregnancy, or prior trauma/injury.

prevent __________. - answerA and B During a quench, patients and employees
