Abstract Background Pediatric patients are in a phase of high anatomical and physiological development, whose characteristics make them more radiosensitive to certain radiation exposures. Exposure doses can lead the occurrence biological effects, including cancer. Objectives To analyze exposures resulting from pediatric radiological examinations perform an optimization process, with purpose adequate use principles protection. Methods The analysis was performed using technical parameters...
The purpose of this study was to estimate the kerma-area product (KAP) and incident air kerma (INAK) in radiographic skull examinations anteroposterior/posteroanterior (AP/PA), lateral (LAT), Towne (TOW) projections from a large paediatric hospital Brazil. In addition, influence thickness on patient parameters technique verified. A total 125 patients (69 males 56 females) were evaluated, 294 radiographs (125 AP 123 LAT, 46 TOW) performed. To analyze results, divided into age groups: 0-1...
Diagnostic and therapeutic interventional cardiology procedures are widely used among paediatric patients to assess congenital pathologies. However, these may provide high radiation doses patients. The data presented in this paper represent the second attempt establish local diagnostic reference levels (DRLs) for air kerma-area product (PKA) first DRLs kerma at patient entrance point (Ka,r) cardiac Brazil. In a period of 3 years (2019–2021), on 135 were evaluated. institutional calculated as...
Paediatric interventional cardiology procedures are performed for the diagnosis and/or therapy of cardiac pathologies. These have shown a growing increase in recent years, as they numerous advantages and less invasive when compared to conventional surgeries. The main disadvantage these is high dose radiation that patients receive during procedures. Such include fluoroscopy mode, which allows real-time visualization cine documentation images. In present study, we evaluated contribution modes...
Abstract X-rays are widely used in medicine, including pediatrics. In addition to the benefits offered by diagnosis, its use may also lead occurrence of biological effects. pediatrics some tissues or organs more radiosensitive. Also, due small size children, very close, increasing radiation dose received patients. This study aimed estimate children Skull AP, Abdomen AP and Pelvis projections. The calculation was performed from x-ray tube output values were compared with major international...
