Abstract

Introduction. Retinoblastoma, a malignant ocular tumor in children, requires cautious imaging due to an increased risk of secondary tumors linked to ionizing radiation. In sub-Saharan Africa, where access to magnetic resonance imaging (MRI) is limited, computed tomography (CT) remains widely used. This study aimed to assess the knowledge of Cameroonian radiology technical staff regarding ionizing radiation exposure levels in children with retinoblastoma. Materials and methods. We conducted a descriptive cross-sectional study from May 2024 to January 2025 among 59 technical professionals working in various radiology departments in Cameroon. Data were collected via an electronic questionnaire and analyzed descriptively. Results. The majority of participants (83.1%) had never encountered a case of retinoblastoma. Only 10.2% were aware of a recommended dose exposure limit for these patients. Paradoxically, 81.4% considered brain CT as an appropriate examination, while 78% correctly identified MRI as the imaging modality of choice. Proposed dose limits varied from 0 mGy to 50 Gy, reflecting great confusion. Conclusion. This study reveals a significant deficit in specific pediatric radiation protection knowledge among radiology staff in Cameroon. The implementation of adapted continuous education programs is imperative to optimize the management of children with retinoblastoma and minimize the iatrogenic risk of secondary tumors.
