The comparison of doses in relation to sex demonstrated that, in spite mifcional higher mean body mass index for girls, the dose on the boys was higher Table 4probably because of the inherent difficulties presented by the male anatomy, and the higher number of abnormal studies in boys, which caused greater time in fluoroscopy, and increase in dose.
The comparison by examiner radiologist showed small differences in the cistouretrogrwfia the examinations were conducted, and highlights the extension of the fluoroscopy time by all the examiners as per Table 5. Spanish term or phrase: This hospital is a reference in neonatology, pediatric surgery and medical genetics; consequently, the number of patients with congenital abnormalities is very high, with frequent cases of urinary abnormalities.
Radiation dose reduction in paediatric fluoroscopy using added filtration. This demonstrates the need for a rigorous quality control in radiological equipment for medical applications, especially in a pediatric hospital.

Setting the fluoroscopy values for current and voltage in a sufficiently low level to allow the identification of the desired structures may result in a considerable reduction of the total dose of the procedure. Only one child might be considered obese, cistouretrgrafia does not influence the average technical factors.
Mean total DAP for radiography and fluoroscopy was separately evaluated for each age group, noticing that in the highest age group, the utilization of larger films and fluoroscopy fields contributes for a larger irradiated area, and consequently, to an increase in the dose Table 3. However, all of them used fluoroscopy for an extended time, increasing the radiation dose delivered to the patient.
Assessment of dosimetric quantities for patients undergoing X-ray examinations in a large public hospital in Brazil – a preliminary study. Ward 20 also suggests that, previously to the examination, the radiologist should obtain the clinical history of the patient and confirm if the indication is correct, or if some other method, such as radionuclide cystogram for example, might be a better indication to clarify the doubts of the assisting physician.
Total DAP ranged from to 1, cGy. One even questioned if there might be an cistouretorgrafia difference in the biometric profile among the children, however, the BMI evaluation showed that the majority of them were low-weight children.
To evaluate dose-area product, skin entrance dose and doses from fluoroscopy and radiography in voiding cystourethrography studies of pediatric patients.
Radiation dose measurement and risk estimation for paediatric patients undergoing micturating cysto-urethrography. The next step is a careful genital antisepsis and introduction of a catheter through the urethra to the interior of the bladder.
cistouretrografía miccional con TV | Spanish to English | Medical: Health Care
Automatic update in The limitation of the fluoroscopy area only to the area of interest, even in equipment with automatic collimation as a function of the programmed film division, could be an cistouretrigrafia dose reducing factor in these higher patients.
View Ideas submitted by the community. The main indications for this imaging method are: Some procedures heterogeneity was observed and guidelines for good radiographic techniques were not followed. This means that all patients must receive the maximum attention in order to minimize the possibility of acute and late biological effects resulting from radiation exposure.
In an important Brazilian Institution of pediatric radiology, the doses are miccionwl those found in similar studies. Vote Promote or cstouretrografia ideas.
Dose and image quality in the comparison of analogue and digital techniques in paediatric urology examinations. Inthe American Academy of Pediatrics AAP recommended perform a renal ultrasonography and avoiding cystourethrography to cistouretrogrsfia infants between 2 and 24 months of age after their first urinary tract infection UTI.
The dose delivered to the patient in voiding cystourethrography is high, with fluoroscopy being its primary contributor. One half the children were one year old or less at the time the examinations were performed. Login or register free and only takes a few minutes to participate in this question. Review native language verification applications submitted by your peers.
In one of the patients included in this age group, fluoroscopy accounted for In the present study, one of the factors that contributed for the magnitude of entrance skin doses was the lack of uniformity of the radiographic imaging techniques employed. One should remember that some radiologists perform the examination without using fluoroscopy, because they have learned to do so, in a time when image intensifiers were not available.
Participation is free and the site has a strict confidentiality policy. Through this catheter, iodinated contrast medium diluted in saline solution is administered, and anteroposterior radiographs are made during the vesical filling, at the low, medium and full filling stages. The routine for examination starts with an abdominal radiograph in anteroposterior projection, with the patient in dorsal decubitus.
However, considering what occurred in the fluoroscopy study, where similar equipment presented very different doses, leading to the finding of a serious problem in one of them which led to its deactivation, one may question if some technical non-conformity might be happening, and thus justify the high doses observed in the present study. Accepted after revision November 14, Most recent studies 19,20 approach the utilization of technically more updated equipment, with the so called pulsed fluoroscopy, which considerably reduces the total dose, by directly influencing the fluoroscopy dose reduction.
Considering these factors and the following variables, a anatomic differentiation, b discrepancy among techniques utilized to obtain pediatric radiographic images and c different doses to which patients are exposed, the European Community has issued the European Guidelines on Quality Criteria for Diagnostic Radiographic Images in Paediatrics 5defining the quality criteria of images for most of these procedures.
Quantifying the radiation exposure determined by an imaging method is a relevant task, especially when this method has such a clarifying meaning as observed in voiding cystourethrography, considering that there is the opportunity to define the actual level of exposure caused by the method and, within the acceptable values to produce a good radiographic image, to correct the application of eventually high doses which many times are caused by the radiologist habit of trying to produce a diagnosis by means of fluoroscopy, forgetting the radiation dose delivered to the patient.
