As the front line in the imaging process, the technologist plays a key role on the imaging team. Nuclear medicine tests are often essential in diagnosing illness in children, impacting their treatment and improving outcomes. You, as the nuclear medicine technologist, plays a key role as an advocate for children. By logging onto this website, you have already demonstrated your commitment to improve radiation protection for kids. It is the collective duty of all members of the healthcare team to ensure that every imaging study in pediatric patients is thoughtful, appropriate and indicated. This website provides simple educational resources to radiology and nuclear medicine practices for improving radiation protection for children. 

5 Simple Steps to Improve Patient Care in Your Daily Practice 

• Be the patient’s advocate. Ask the questions required to ensure that you “child-size” the study. 
• Be committed to make a change in your daily practice by working as a team with the nuclear medicine physician, physicist, referring physicians and parents to decrease the radiation dose! 
• Use optimal imaging protocols and post-processing techniques. 
• As you work to decrease the administered dose to children, you also reduce your dose and the dose to your fellow technologists! 
• Follow expert guidelines:

Patient Preparation

• Appropriate patient preparation is crucial for image quality. Any measure that can calm the child prior to start of imaging will help keep the child quiet and still during the imaging study.

• Different imaging studies warrant certain protocols; please see the following references below for more details.

Radiation Dose and Risk

• Radiation dose may differ among children as compared to adults due to patient size, organ size and orientation and organ distribution of administered radiopharmaceutical.
• Estimates of critical organ and effective dose in common pediatric nuclear medicine procedures are listed in the table below. However, please note that these estimates are averages over a wide range of patients at each age and do not take into consideration individual differences in anatomy and physiology from the standard models.
• Assessing the risk associated with exposure to ionizing radiation involves applying models that use both epidemiologic and biologic data to extrapolate from the available data to the dosimetric region of interest. Such extrapolation is not straightforward.
• Much of the current understanding about the risk of exposure to ionizing radiation for humans is based on the Life Span Study of the survivors of the bombings of Hiroshima and Nagasaki as reported by the Radiation Effects Research Foundation.
• The consensus is to assume that the risk at the lower doses with medical radiation can best be estimated by a linear extrapolation from higher doses for radiation protection purposes.
• It has become increasingly more important that nuclear medicine practitioners—including physicians, physicists, technologists and other members of patient care teams—effectively communicate with the referring providers and with patients and families about the medical use of radiation, the level of radiation exposure and the potential risk.
