when it comes to any form of Pediatric
Care the health and well-being of the
young patient is always the first
priority and that does not change when
it comes to radiologic Imaging
Radiology as a whole is primarily known
for producing really cool x-rays that
shows parts of our bodies that we cannot
see from the outside this includes our
bones brain parts of our organ systems
like our kidneys liver and more
what a lot of people do not know however
are the dangers and risks that come with
x-rays
the most important thing when it comes
to acknowledging the risks of X-rays and
CT scans is knowing what makes these
machines potentially hazardous
these tools work by using ionizing
radiation which operate by using
particles of light to remove electrons
from molecules of materials that we
cannot see these materials can be air
water and living tissues which include
our skin without the proper care and
without the proper dosage of radiation a
few things can happen one of the major
ways that radiation can potentially
affect the patient is by changing their
DNA by inducing DNA breaks and or single
strand breaks from the ionizing
radiation
if the dosage is too high a patient can
be diagnosed with acute radiation
syndrome or more commonly known as
radiation sickness a patient can also suffer from radiation
Burns which in severe cases is usually
named radiation dermatitis so with all of these risks when it comes
to radiologic Imaging our predecessors
realize that the radiologic standards
for children should not be the same as
adults a big reason being that the thickness of skin compared to an adult
is not the same as on a child which
means radiation can penetrate the
child's game far easier due to it being
thinner
our predecessors knew that the dosalara
or as low as reasonably achievable
dosage of radiation had to be much lower
when it comes to radi when it comes to
Imaging children
this led to radiologies wanting to
protect kids as best as they can if they
need an x-rays or CT scans or any other
procedure involving ionizing radiation
because of the innate need to protect
image gently was founded and created in
2007 to promote safe Imaging in children
their mission statement reads as follows
the mission of the Imaging Alliance is
through advocacy to improve safe and
effective Imaging care of children
worldwide
image gently was founded by what I like
to call the four founding parent
organizations these organizations
include the society for Pediatric
Radiology the American College of
radiology the American Society for
radiologic Technologies and the American
Association of physicists and Medicine
even though a lot of these organizations
and even image gently itself was founded
in America image gently is a global
organization with ties in New Zealand
Britain Italy Australia India and
Argentina just to name a few
their main goal is to raise awareness of
the multitude of opportunities that are
made available to lower the dosage of
radiation while Imaging children
on the msgently website there's a
plethora of information for not only
technologies that are entering the
Radiology field but for physicists and
parents as well
this is a great way to help parents
understand what exactly is happening
during the Imaging process so that there
is less concern and they feel a bit more
content with knowing what's happening
they have specifications for computed
tomography Interventional procedures
nuclear medicine and ultrasounds
overall image generally is a great
source in program when it comes to
advocating for the safe Imaging of our
children
there's plenty of information that can
be found on their website msgently.org
all of this is to help parents and
technologists alike help to protect
children and provide them with the best
possible care
Medical imaging is widely used in the diagnosis and management of many medical conditions. Imaging often utilizes radiation, and this exposure raises questions and concerns from patients and providers alike. When considering medical options, providers need to clearly explain potential risks and benefits, critically appraise the available literature for evidence-based recommendations, positively influence their
healthcare team’s actions and share the informed decision-making process with their patient and family.
This innovative module utilizes radiation protection in children as a framework to emphasize:
layperson terminology as a crucial bridge to close the health literacy gap,
clinical decision support and critical appraisal skills to encourage evidence-based practice,
motivational interviewing to empower learner-directed change with patients and colleagues,
and shared decision-making to promote respectful healthcare.
The Image Gently Family-Friendly Campaign module is a free interactive learning experience, built by an interprofessional, interdisciplinary team made up of Family Medicine and Pediatric Radiology physicians, radiology technologists, medical physicists, health professions educators and medical students.
The module was ideally designed for medical students in their Family Medicine clerkship. It would also fit
well within a Pediatrics clerkship or a Radiology rotation. However, we expect that it could be beneficial for residents and attending physicians, alike. We anticipate it will take one hour to complete the course.
1.
Children are smaller than adults.
For any given set of CT scanning parameters, the effective dose is higher for smaller cross-sectional areas. This is because dose is defined as absorbed energy per unit mass, and therefore the same energy in a smaller mass will result in a higher dose per unit mass. In addition, in the case of CT, where the beam is applied circumferentially, dose in the center of a small patient will be higher than in the center of a large patient, due to the lesser attenuation of the surrounding tissue in a small patient. These
effects will be most pronounced in the youngest patients with smaller body mass and radius. Calculated dose parameters that are displayed in current CT scanners are based on data

obtained from the 32 cm phantom. In an average adult, whose size is equivalent to 29 cm, the 32 cm acrylic phantom will underestimate the dose to that average adult by approximately 30% [10]. This, of course, would be compounded in pediatric patients. In an analysis of effective dose by body mass, effective dose in pediatric patients was increased by 50% compared to adult patients despite a reduction of approximately 25% in scanning parameters in that series. The increase was most marked in the infants, in whom effective dose increased 100% [10]. It is therefore very important to realize that, for a given set of CT scanning parameters, we must CHILD-SIZE the scanning parameters just to maintain the same image noise that is acceptable in the CT images of our adult patients.

Children are growing.
Because of this, their tissues are more radiosensitive than adult tissue. According to the International Commission on Radiation Protection (ICRP), estimates of attributable lifetime risk for a single dose of radiation vary considerably with age, are increased in patients younger than 30 years, but particularly in patients younger than 10 years [11]. With the exception of leukemia, girls are also believed to be more radiosensitive than boys for most cancers, particularly breast and thyroid. This increased radiosensitivity is believed to be related to other promoting factors which are hormone-dependent and which differ between males and females, rather than to other potential inherent differences in radiation sensitivity
