Evaluation of Pediatric Imaging Modalities Practices of Radiologists and Technologists: A Survey-Based Study

Abstract

Introduction Radiation protection for pediatric patients is the main concern in pediatric computed tomography (CT) due to their sensitive organs, such as the brain and the thyroid glands. Accordingly, an optimization of pediatric CT practices is vital to minimize the radiation dose for this population. Aim To assess the pediatric CT practices of radiologists and technologists in a CT unit. Materials and Methods The study was conducted among 26 hospitals, located in various regions in Saudi Arabia. A total of 200 hard copies of the questionnaire were distributed manually and were collected for analysis. In total, 117 completed surveys were gathered from technologies, while 49 were gathered from radiologists. Results In the case of infants with hydrocephalus, 65% of the radiologists ordered an ultrasound (US), 24% ordered a head CT scan, and 10% ordered a magnetic resonance imaging (MRI) and general X-ray for diagnosis. For pediatric patients complaining of persistent headache, 59% and 27% of the radiologists recommended CT and MRI, respectively, for diagnosis. Conclusion Most of the radiologists utilize CT head scan to diagnose persistent headache (by 59%) and ventriculoperitoneal shunt (VPS) malfunction (by 41%) in pediatric patients compared with the other modalities. The use of CT can increase the risk of later malignancy among pediatric patients due to radiation exposure. Alternative imaging modalities such as US and MRI (non-ionized radiation) should be considered to reduce the ionizing radiation hazards and optimize the current practices of radiologists. Most of the technologists follow radiation protection protocols in this study as 63% of the technologists used lead apron for pediatric patient’s protection. Radiation awareness training for the technologists could improve the knowledge about the benefits of using lead apron and reduce the radiation risks in pediatric patients.

Assessment of diagnostic reference levels for paediatric cardiac computed tomography in accordance with European guidelines

“…Children are more vulnerable (UNSCEAR 2013 ) to the harmful effects of radiation than adults, making paediatric exams a particular source of concern. Recent studies have shown an increase in cancer incidence following paediatric CT scans (Tajaldeen et al 2022 ). Due to a longer life expectancy and higher radiation sensitivity, children are suffering a higher risk of radiation damage than adults (Tsai et al 2008 ).…”
