 Shady Grove Radiology is committed to the Image Gently campaign, which is designed to raise awareness of the need to minimize radiation exposure to children undergoing imaging procedures, especially CT scanning.
Members of the Society for Pediatric Radiology (SPR) realized that there was a need for widespread educational and public awareness of the differences between the effects of radiation in children and adults. The utilization of CT has increased dramatically over the past decade and children have many more years than adults to experience the effect of radiation exposure. Clearly CT Scanning has been used to diagnose many specific pediatric conditions that would otherwise not be diagnosed or not diagnosed as efficiently.
Imaging practices such as ours are committed to image gently. We have reviewed our techniques in order to “child/size” the amount of radiation that is used and in fact, we encourage that CT be used
only when necessary.
In order to make it convenient for patients to keep track of their child’s medical imaging records, we are distributing wallet size and larger imaging records so that each time a child has an examination performed, it may be recorded. We encourage parents to have this data with them at all times so that if they are in need of an imaging study, or if they find themselves in an emergency room or hospital setting, they can refer to this record , and when appropriate share with this information with the treating physician who may use this information to decide whether or not a CT scan is truly needed.
We encourage everyone to visit the www.Imagegently.org website to obtain additional information. Any of our radiologists are available for your consultation prior to ordering any imaging study.

Our radiologists and technologists are pledged to:
- Making a change in our daily practice by working as a team with radiologists, physicists, referring doctors and parents to decrease the radiation dose.
- Knowing practice standards and using them as a guide to ensure the appropriate action plan is established for completing a CT exam.
- Working with our physicists and radiologists, reviewing CT protocols. We have “down-sized” protocols for kids. More is not better; adult-size radiation exposure is not necessary for small bodies.
- Be involved as the patient’s advocate. To ask questions as required to “child-size” the scan, and to scan only the area required to obtain necessary information.

Alternatives to CT
 Medical imaging has changed the practice of medicine, and many diagnoses are made or confirmed on the basis of imaging tests. Computed tomography (CT) is a valuable and readily available way to diagnose a variety of conditions, which explains its popularity and increased use over the last 20 years. Recent evidence indicates that CT performed in children carries a small but real increased risk of cancer later in life, and that this risk is larger for younger patients. This does not mean that CT should never be performed; it is often the best test in many situations and can provide valuable and even life-saving information. However, in many cases there are other ways to obtain the same medical diagnostic information without exposing a child to radiation by using ultrasound (US) or magnetic resonance imaging (MRI).
 Ultrasound is particularly valuable in children, since their smaller size and lesser body fat allows for high quality and high resolution imaging. Instead of passing x-rays through the body, US uses pulses of sound to create images. Images are obtained by placing an US transducer (also called a probe) on the child using a special gel that allows the sound waves to get through the skin. US can image almost any area of the body; the only limitations are that US cannot “see” through bone or air. US can also provide information about blood flow, and thus can help evaluate the function of organs as well as their anatomy. A criticism of US is that it is very dependent upon the skill and care of the person performing the examination. Questions you can ask your imaging provider include whether or not the sonographers performing the examination are credentialed, is the ultrasound department credentialed, and whether or not the interpreting physicians have special training and education in ultrasound.
Magnetic resonance imaging creates images of the body by using magnets and radio waves, and does not expose patients to radiation. The main disadvantage of MRI in children is the need for the patient to be very still, as even small amounts of motion will ruin the image. This means that younger children often need sedation, which requires specialized equipment and staff training not available from all imaging providers. Newer and faster MRI techniques are helping to lessen problems from patient motion, and coaching and distraction techniques can help even very young children successfully complete an MRI exam. Again, questions to ask your imaging provider include whether or not the technologists are registered, is the facility accredited for MRI, and are the physicians involved specifically trained in sedating and imaging children. |
US and MRI are non-radiation methods of imaging that provide important diagnostic medical information. Depending upon the clinical situation, CT may still be the best and most reasonable study. Properly performed, the potential risks of CT can be minimized, and the small potential risk worth the information obtained. In some situations, US or MRI may be equally viable imaging options, without imposing the even small risk of problems later in life. If you think that US or MRI might be an option for your child, you should ask your child’s clinical or imaging physician. Information about CT is available on this website.
