Avaliação dos padrões de dose em radiologia pediátrica

Abstract: Lima AA et al. Radiol Bras 2004;37(4):279282279 gica, ou seja, todos os pacientes devem receber a máxima atenção no intuito de minimizar a possibilidade de ocorrência de efeitos biológicos agudos e/ou tardios, resultantes das exposições a esta radiação. Deste modo, se a proteção radiológica de pacientes expostos à radiação ionizante é importante, esta o é, sobretudo, nos pacientes pediátricos (3,6-10) . A Comunidade Européia, considerando esta situação e as seguintes variáveis -a) diferenciação anatômica; b) d… Show more

“…According to the Evaluation of dose patterns in pediatric radiology [ 12 ], sample calculations considered differences significant when there was a significance level of ≤5%, with 80% of power with a standard deviation of 0.026 for the Dose Area Product (DAP) or Entrance Skin/Surface Doses (ESDs) in μGy, and an expected difference of 0.01 in mGy. The total number of subjects was 48, and 48 radio-photographic images were analyzed.…”

“…To correlate the radiation doses, in relation to the thoracic diameter of each group, a Spearman correlation coefficient was used. The sample size calculation was based on similar studies [ 12 , 13 ]. For statistical analyses, SPSS and Minitab statistical software were employed.…”

“…Vários estudos vêm sendo realizados com este propósito, tanto no exterior (7,8,9) como no Brasil (10,11,12,13) . Os fatores de retro-espalhamento foram estimados por vários autores utilizando métodos diferentes, como câmaras de ionização, dosímetros termoluminescentes e o método de Monte Carlo (14,15,16) .…”
