• Abstract: Computed tomography (CT) is one of the radiology modalities that has seen the most technological advances in the last decade, meaning its use has consequently become increasingly routine. These advances allow exams to be carried out with higher quality and take less time compared to the equipment of the first generations. These reasons somehow justify the widespread use of tomography, being responsible for approximately 43% of the global collective dose of ionizing radiation from radio diagnostic means (UNSCEAR, 2010). However, it is necessary to pay attention to this consequence, the increase in radiation doses for patients, especially for the group of pediatric patients, who, as they are still in the growth phase, have more impactful biological effects. Studies on this topic are extremely important to measure and be able to take measures that optimize the doses received by patients, in order to increasingly perform exams with good diagnostic quality without unnecessarily irradiating the pediatric patient. Each study and experiment carried out arrives at different answers, such as protocol inconsistency, non-optimized doses, patient movement and possible human errors. By combining several studies, it is possible to achieve methods that allow the correct use of computed tomography, especially for pediatric patients.
