MRSO EXAM PREP NEWEST 2026-2027
QUESTIONS AND CORRECT ANSWERS |
BRAND NEW A+ GRADE STUDY GUIDE
ACR Guidelines for orbit screening: Correct Answer "All
patients who have a history of orbit trauma by
a potential ferromagnetic foreign body for which
they sought medical attention are to have their
orbits cleared by either plain X-ray orbit films
(2 views) or by a radiologist's review and
assessment of contiguous cut prior CT or MR
images (obtained since the suspected traumatic
event) if available."
ACR Guidance on MR Safe Practice
Pg 6
FDA - MRI Safety during pregnancy Correct Answer FDA -
The safety of MR imaging during pregnancy
has not been proved.
ISMRM - MRI Safety during pregnancy Correct Answer
ISMRM-
"MR Imaging may be used in pregnant women if
other nonionizing forms of diagnostic imaging are
inadequate or if the examination provides
important information that would otherwise require
exposure to ionizing radiatio
,ACR - MRI Safety during pregnancy Correct Answer Can
be accepted at any stage of pregnancy. Level 2-
designated attending radiologist to confer with ordering
physician and determine that the risk-vs-benefit ratio to the
patient warrants the study
What needs to be documented in the pregnant patient's
chart? (3) Correct Answer 1. The information requested
from the MR study cannot be acquired by non-ionizing
means (ultrasonography)
2. The date is needed to potentially affect the care of
either the patient or the fetus during the pregnancy
3. The referring physician feels it is not prudent to wait
until the patient is no longer pregnant to obtain this data.
ACR states informed consent in pregnant patients is / is
not required Correct Answer is not required.
Gadolinium use with pregnant patients Correct Answer
Should not be routinely used in pregnant patients
The decision to use gadolinium contrast in a pregnant
patient must be made by Correct Answer Case-by-case
decision made by level 2 MR
personnel-designated attending radiologist who will
assess the risk-benefit ratio for the particular patient and
accompanied by a well-documented and thoughtful risk-
benefit analysis
, Pregnant MRI staff Correct Answer Permitted to work in
and around the MR environment throughout all stages of
their pregnancy. May perform all job-related duties
Requested not to remain with the scanner bore or Zone IV
during active scanning
The use of ferromagnetic detection systems is
recommended as an adjunct to Correct Answer thorough
and conscientious screening of persons and devices
approaching Zone IV
The use of metal detectors in MRI is Correct Answer
discouraged
How do ferromagnetic detectors work? Correct Answer
Ferromagnetic detectors "monitor" the surrounding
magnetic fields. When something ferromagnetic moves it
distorts the surrounding
magnetic field, Ferromagnetic detectors sense
that change.
List 3 types of ferromagnetic detectors used in MRI
Correct Answer Single pillar (screener), hand held (not for
full body screening), doorway (less sensitive - best for
large metallic objects)
Where should pillar ferromagnetic detectors be located?
Correct Answer In zone 2 - before zone 3.
How should MR staff dress? Correct Answer
Ferromagnetic free
