Computed Tomography Angiography (CTA) is a valuable non-invasive tool for assessment of congenital heart disease in neonates. Though it requires less radiation, contrast and sedation than catheter angiography, which is the current standard of care, traditional CTA can still necessitate significant radiation dose, sedation, breath-holding and/or low heart-rates to achieve diagnostic studies. In this frequently imaged neonatal patient population, it is imperative to minimize cumulative radiation to limit the lifetime risk of cancer. At our institution, we have successfully used a new fast-acquisition FLASH CTA protocol to achieve high quality imaging of neonates with complex congenital heart disease with minimal radiation dose and without sedation.

The use of pediatric abdominal CT has been increasing rapidly. However increased radiation exposure is a public health concern for children because of children are more sensitive to radiation than adults. The purpose of this study is to estimate which patient-related factors affect radiation dose, to pediatric patients undergoing abdominal CT Read More

Fetal CT has almost the same utility as a postnatal skeletal survey. Despite this benefit, the associated radiation exposure is disadvantageous and radiation dose reduction is mandatory. It is however impossible to measure the actual radiation dose to the fetus directly. Several previous reports have described the CT dose index (CTDI) volume and dose length product (DLP) as representing an imagined fetal dose. The actual fetal radiation dose needs to be confirmed using a phantom that practically corresponds to a pregnant woman. Read More

We developed a free iOS application, RADiDOC, with the goal of simplifying the complex subject of medical radiation risk for pediatric patients and their parents. Utilization of medical imaging has risen over the past decade, making the topic of radiation safety an increasingly important issue that is increasingly featured in the popular media. Furthermore, given the unique risk profile of radiation exposure in the pediatric age group, there has been increased focus on the judicious use of ionizing radiation in the imaging of children. These efforts have resulted in the Image Gently campaign, which has offered an immense contribution to pediatric radiation safety issues.

In keeping with these efforts, we created the RADiDOC application to help pediatric patients and their parents understand key radiation safety information in a simple, intuitive way. To meet these ends, RADiDOC was created with three core functionality modes: (1) Consultation, (2) Radiation Log, and (3) Radiation 101. Consultation mode allows users to explore a multitude of imaging studies and image-guided procedures and learn about their associated radiation risk, including quantitative cancer risk estimated using the BIER VII dataset. To be more meaningful to patients, dose is described not only in terms of “effective dose” and its associated ACR category, but also in terms of intuitive measures such as the equivalent number of transatlantic flights and days of natural sun exposure. The Radiation Log mode allows patients or their parents to log additive radiation risk from all imaging received in their lifetime, creating a longitudinal radiation log of lifetime exposure. This may be of particular interest to pediatric oncology patients who receive long-term serial imaging. Finally, Radiation 101 offers a primer on the basics of radiation safety and radiation physics aimed at a broad audience of laypeople.

RADiDOC offers a free resource to facilitate the discussion of radiation risk between pediatric radiologists, clinicians, pediatric patients, and their parents. In this Technical Development presentation, we review key radiation safety concepts and elaborate on the core functionalities of this application and how it can be of use to pediatrics radiologists and their patients.

To diagnose intestinal disease or guide an injection treatment, radiation from a fluoroscopy exam is often nontrivial. In addition to regulatory and accreditation requirements, it is clinically important to establish a mechanism to review and improve the use of fluoroscopy, particularly for pediatric patients who are more sensitive to radiation than adults. In this study, we aimed to implement a fluoroscopy dose monitor program, assess overall fluoroscopy performance, and evaluate radiologist performance, in a pediatric hospital system. Read More
