Radiation dose reduction in paediatric fluoroscopy using added filtration.
cistouretrografía miccional con TV
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. The comparison by examiner radiologist showed small differences in the way the examinations were conducted, and highlights the extension of the fluoroscopy time by all the examiners as per Table 5.
The dose delivered to the patient in voiding cystourethrography is high, with fluoroscopy being its primary contributor. The patients were divided into four age groups: Login or register free and only takes a few minutes to participate in this question.
Patient dose reduction during voiding cystourethrography. Reviewing applications can be fun and only takes cjstouretrografia few minutes. Mean values for voltage kV and load mAs obtained in the examinations were 72 kV and 6. Higher patients or those in the higher age ranges require larger films to document the images, which in certain instances should include the whole collecting system from the bladder to the kidneys. Radiation dose measurement and risk estimation for paediatric patients undergoing micturating cysto-urethrography.
Accepted after revision November 14, Paediatric x-ray examinations in Rio de Janeiro. Pediatric radiation exposure and effective dose reduction during voiding cystourethrography. A comparison of doses and techniques between specialist and non-specialist centres in the diagnostic X-ray imaging of children.
Considering that the fluoroscopy time ranged from 82 to 1, seconds mean, secondsthe authors can suggest a radical reduction of this time. Thus, if radioprotection of patients exposed to ionizing radiations is important, it is moreover so, with pediatric patients 1,2.
Their weight ranged cistoruetrografia 2. The next step is a careful genital antisepsis miccinal introduction of a catheter through the urethra to the interior of the bladder.
Micciional 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.
Considering the predominantly pediatric profile of the institution, the present study is aimed at analyzing the radiation doses to which children are exposed during voiding cystourethrography.
However, all of them used fluoroscopy for an extended time, increasing the radiation dose delivered to the patient.

One half the children were one year old or less at the time the examinations were performed. Dose-area product values in frequently performed complex paediatric radiology examinations. 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, 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. Cistouretrgorafia the values found were discrepant, ranging from 0.
The prevalence of a relevant pathology among patients studied as cistourerografia the guidelines 9 out of 24 cases, 3 with atypical UTI or as per the guidelines 11 out of 21 cases was similar In one of the patients included in this age group, fluoroscopy accounted for Post Your ideas for ProZ. Only one child might be considered obese, which cistouretrogeafia not influence the average technical factors.
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.
Dose and image quality in the comparison of analogue and digital techniques in paediatric urology examinations. These images will allow the evaluation of a possible vesicoureteral reflux, of the contents and of the bladder wall.

Received October 31, Which is the best way of performing a micturating cystourethrogram in children?
Login to enter a peer comment or grade. One even questioned if there might be an expressive difference in the biometric profile among the children, however, the BMI evaluation showed that the majority of them were low-weight children.
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 additional dose reducing factor in these higher patients. Close and don’t show again Close. The KudoZ network provides a framework for translators and others to assist each other with translations or explanations of terms and short phrases. Some procedures heterogeneity was observed and guidelines for good radiographic techniques were not followed.
Estimation of adult patient doses for common diagnostic X-ray examinations in Rio de Janeiro, Brazil. For being anatomically related with the genital area where the ovaries that cannot be protected and testicles that can be partially protected from the inherent high examination dose by means of gonad protectorsthis imaging method causes a great exposure of these structures that are so sensitive to radiation.

In a review of similar studies in developed in other countries, one can miccipnal evaluate such difference. Voiding cystourethrography is considered the standard method in the evaluation of vesicoureteral reflux and malformations of the urethra and bladder 4. At the first years of life, the patients tend to be more active during the examination and, consequently, end up staying longer under fluoroscopy, which also contributes to citsouretrografia higher final dose.
The dose delivered by a determined radiological examination reaches its maximum on the surface of the irradiated area.
