Assessment of dosimetric quantities for patients undergoing X-ray examinations in a large public hospital in Brazil – a preliminary study. You have native languages that can be verified You can request verification for native languages by completing a simple application that takes only a couple of minutes.
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. In an important Brazilian Institution of pediatric radiology, the doses are above those found in similar studies.

Their weight ranged from 2. The utilization of high-kilovoltage and low-milliampere techniques, as well as fluoroscopy only for positioning the patient and observing the cistouretrografiz remarkable alterations, will certainly result in an important dose reduction.
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.
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. Term search All of ProZ. One half the children were one year old or less at the time the examinations were performed. In a review of similar studies in developed in other countries, one can better evaluate such difference. These images will allow the evaluation of a possible vesicoureteral reflux, of the contents and of the bladder wall.
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. In this latter hospital, the fluoroscopy time ranged from 0. Login to enter a peer comment or grade. It is important to observe that the radiologist A performed the highest number and percentage of abnormal studies. Saudi J Kidney Dis Transpl. Evaluation of radiation dose in voiding cystourethrography in children. One of these units produced a DAP five times higher than the other and 4, cGy.
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. Spanish term or phrase: Dose-area product values in frequently performed complex paediatric radiology examinations. Reviewing applications can be fun and only takes a few minutes. The observation of total ESD ranging from 17 to Mean values for voltage kV and load mAs obtained in the examinations were 72 kV and 6.
Forty-five patients 31 girls were included and were grouped as if they had been treated as per the or guidelines. Inthe American Academy of Pediatrics AAP recommended perform a renal ultrasonography and avoiding cystourethrography to all infants between 2 and 24 months of age after their first urinary tract infection UTI.
View forum View forum without registering on UserVoice. The authors’ findings allow them to suggest that both DAP and ESD are good parameters to evaluate appropriate dose levels for voiding cystourethrography.

Thus, if radioprotection of patients exposed to ionizing radiations is important, it is moreover so, with pediatric patients 1,2. Procedures performed in 37 patients by four physicians of the institution were evaluated. A comparison of doses and techniques between specialist and non-specialist centres in the diagnostic X-ray imaging of children. 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.
In the present study, in one study, the fluoroscopy time reached more than micional minutes, perhaps justified by the problems of the patient affected by spine deformity, with severe scoliosis causing extreme difficulty in the manipulation of the region for images acquisition. In one of the patients included in this age group, fluoroscopy accounted for Pediatric radiation exposure and effective dose reduction during voiding cystourethrography.
Which is the best way of performing a micturating cystourethrogram in children? This demonstrates the need for a rigorous quality control in radiological cistourdtrografia for medical applications, especially in a pediatric hospital.
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.
Quantifying miiccional 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 miccioonal 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.
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.
Close and don’t show again Close. One can determine the radiation dose incident on the exposed areas by using the Diamentor, a device that is coupled to the x-ray tube that allows the monitoring of accumulative radiation emitted by the x-ray tube during the examination, and which will not interfere on the procedure performance.
The main indications for this imaging method are:
