Diagnostic reference levels (DRLs) are a pivotal strategy to be implemented since pediatric interventional cardiology procedures increasing. This work aimed propose an initial set of Brazilian DRLs for diagnostic and therapeutic (D&T) procedures. A retrospective study was carried out in four states, distributed across the three regions country. Data were collected from patients undergoing cardiac (CIPs), including their age anthropometric characteristics, at least parameters (number...
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...
Fluoroscopic barium meal (BM) studies are largely used around the world and very common to be performed in children. The medical occupational exposures important parameters that need investigated evaluate radiological effects. Calibration of dosimeter for exposure measurement is usually done with primary X-ray beam. difference energy spectra scattered radiation can influence obtained results. main objective this work by different pediatric phantoms (simulation patients subjected BM...
Objetivos: Desenvolver dois suportes para auxiliar na realização de exames joelho, nos quais são necessárias aquisições imagens radiográficas axiais da patela.
 Materiais e métodos: Os protótipos foram construídos testados com base nas medidas antropométricas coletadas pacientes voluntários, do equipamento raios-X Laboratório Radiologia UTFPR (Brasil). Um suporte teve a função acomodar os joelhos o outro receptores imagens.
 Resultados discussões: materiais selecionados confecção...
Os exames de tomografia computadorizada (TC) crânio são amplamente realizados por fornecerem imagens com alta qualidade diagnóstica. No entanto, estes têm contribuído uma grande parcela da dose devido às exposições médicas, chegando até dois terços das doses relativas na população. Deste modo, procedimentos e otimização se tornam fundamental em TC. A avaliação fornecida nesta modalidade diagnóstica é realizada meio do índice volumétrico (CTDIvol). Este trabalho teve como objetivo avaliar o...
To compare inter-rater reliability, diagnostic accuracy, and extension of pulmonary involvement in children with suspected COVID-19 submitted to supine or lateral decubitus computed tomography imaging.Retrospective study carried out between March 2020 2021 patients reverse transcription-polymerase chain reaction testing chest tomography. Patients were divided into two groups: imaging. Standardized reporting systems tomographic findings score used.One hundred seventeen enrolled. Moderate...
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...
