Pediatric radiology education for pediatric and radiology trainees and practicing professionals must be adapted to the target audience. In efforts to narrow the gaps in global pediatric radiology education, the Children's Hospital of Philadelphia's radiology department's Global Outreach and Education Program has designed specific interventions and curricula according to different levels of training and desired expertise. Our initiatives include an online "Introduction to Pediatric Imaging" lecture series for pediatrics residents in Botswana, Ethiopia and Vietnam; access to a learning management system (Outreach RADIAL) for radiology residents; case-based review sessions for pediatric radiology fellows; and in-person seminars for professionals from Eastern Europe and Africa. Here, we highlight our global education efforts to encourage other departments to take a similar systematic approach to outreach activities. [ABSTRACT FROM AUTHOR]

BACKGROUND፡ The thyroid, along with the breast, lung, and bone marrow, is among the most radiosensitive organs. This study aims to assess the rate of unnecessary radiation exposure to the thyroid gland in patients who had chest Computed Tomography (CT) at a large teaching hospital. METHOD: Hospital-based retrospective cross-sectional study on 1,306 patients who underwent chest CT from July 2018 to January 2019. Thyroid gland inclusion along with the CT dose of the studies was evaluated. Data was collected by evaluating chest CT scans from Picture Archive and Communication System (MedWeb). RESULT: Out of 1306 patients, who had Chest CT scans intravenous iodinated contrast media was used in 95.4% of the CT scans. The thyroid was included in 99.8% of the scans, out of which 76.9% included the whole thyroid gland. Among the patients who had previous CT scans, 75.3% had one previous scan and 24.7% had two previous scans. DLP (Dose Length Product) in mGycm was lower in females (360.33±32) compared to males (426.45±378.4). The lowest DLP value was observed in the pediatric patients in the age range of 1-5 years which was 146.83, while the highest was observed among those above 18 years of age with mean DLP of 418.31. CONCLUSION: The majority of chest CT scans unnecessarily include the whole thyroid gland, which is one of the most sensitive organs for radiation-induced effects. Authors recommend optimized technique for chest scans to avoid future impacts. [ABSTRACT FROM AUTHOR]
