MRSO UPDATED COMPREHENSIVE EXAM
QUESTIONS AND ANSWERS SURE A+
✔✔Drug patches in the area of a transmit / receive coil should be - ✔✔removed prior to
scan
✔✔.
ACR Guidelines for orbit screening: - ✔✔"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 - ✔✔FDA -
The safety of MR imaging during pregnancy
has not been proved.
, ✔✔ISMRM - MRI Safety during pregnancy - ✔✔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 - ✔✔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) - ✔✔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 - ✔✔is not
required.
✔✔Gadolinium use with pregnant patients - ✔✔Should not be routinely used in
pregnant patients
✔✔The decision to use gadolinium contrast in a pregnant patient must be made by -
✔✔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 - ✔✔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 - ✔✔thorough and conscientious screening of persons
and devices approaching Zone IV
✔✔The use of metal detectors in MRI is - ✔✔discouraged
✔✔How do ferromagnetic detectors work? - ✔✔Ferromagnetic detectors "monitor" the
surrounding magnetic fields. When something ferromagnetic moves it distorts the
surrounding
