SMRT Educational Seminars
Update: Safety in MR Examinations
Volume 8, Number 3
The SMRT Educational Seminars
(Volume 8, Number 3), has been approved for 2.5 Category A
Continuing Educational credits.
Read the SMRT Educational Seminars (Volume 8, Number 3),
"Update: Safety in MR Examinations" and complete
the quiz and official Answer Form at the back of the article. To
receive credit the quiz must be completed with a score of 75% or
better. Completion of all questions with a passing score will earn a
total of 2.5 category A Continuing Education credits.
SMRT members should send the completed
Answer Form to the SMRT Education Department for scoring. The
certificate will state the CE reference number and awarded CE
credits. Members receiving a score less than 75% will be notified
and given the option of taking the quiz an additional two times.
Members should retain their CE Certificate for their Continuing
Education registry requirements.
- To outline the key items for developing and maintaining a
safe MR clinical environment.
- To review the design and implementation of MR safety and
screening policies and procedures appropriate for your
department and patient population.
- To develop MR safety training for staff and the regular
auditing of safety practices.
- To understand the mechanisms involved with radiofrequency (RF)
absorption, specific absorption rate (SAR), and the resultant
heating of conductors including human beings.
- To review current safety standards set down by the FDA, CDRH,
and IEC which are implemented on MR systems and utilized by
technologists and radiographers.
- To learn RF heating mechanisms of imaging coils and the
potential for induced electric currents.
- To discuss the maintenance of safety in conductive objects
by minimizing local RF heating to prevent RF burns in MR
- To provide a basic understanding of the procedures involved
to optimize MR imaging in children.
- To learn the safety aspects of pediatric MRI especially
pre-examination screening, auditory concerns and contrast
- To develop a program to assist children in coping with the
MRI examination utilizing several methods including
communication techniques, reflecting and reacting to children,
distraction techniques and environmental issues.
- To understand image quality issues including SNR, CNR, and
spatial resolution and the artifacts that are a direct
reflection of the child’s physiological state while under
sedation or general anesthesia.
