One half the children were one year old or less at the time the examinations were performed.

Total DAP ranged from to 1, cGy. Vote Promote or demote ideas. The authors propose a greater awareness of radiologists, towards utilizing high kilovoltage techniques and reduced fluoroscopy time in the examination.

The next step is a careful genital antisepsis and introduction of a catheter through the urethra to the interior of the bladder. Dose-area product values in frequently performed complex paediatric radiology examinations.

Paediatric x-ray examinations in Rio de Janeiro. 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. Procedures performed in 37 patients by four physicians of the institution were evaluated.

European guidelines on quality criteria for diagnostic radiographic images in paediatrics. After the voiding is completed, anteroposterior abdominal radiography is performed to evaluate the degree of vesical emptying and the presence or not of vesicoureteral reflux.

Measurements were performed with an equipment including an ionization chamber directly coupled to the x-ray tube window and an electrometer Diamentor connected to a computer for data collection.

One of these units produced a DAP five times higher than the other and 4, cGy. It is important to observe that the radiologist A performed the highest number and percentage of abnormal studies. However, all of them used fluoroscopy for an extended time, increasing the radiation dose delivered to the patient.


The adoption of radiography with high kilovoltage technique and restricted utilization of fluoroscopy can result in a significant reduction of doses during this procedure, considering that the major contribution to the final dose comes from fluoroscopy.

Reviewing applications can be fun and only takes a few minutes. Forty-five patients 31 girls were included and were grouped as if they had been treated as per the or guidelines. Received October 31, Review native language verification applications submitted by your peers. The body mass index BMI was calculated and ranged from Login to enter a peer comment or grade. On average, 11 radiographies are performed for each study, with extended fluoroscopy time delivering a higher average final dose than those reported in the literature.

Pediatric radiation exposure and effective dose reduction during voiding cystourethrography. The main indications for this imaging method are: English PRO pts in category: Assessment of dosimetric quantities for patients undergoing X-ray examinations in a large public hospital in Brazil – a preliminary study.

In the present study, one of the factors that contributed for the magnitude of entrance skin doses cistouretrogrxfia the lack of uniformity of the radiographic imaging techniques employed. In one of the patients included in this age group, fluoroscopy accounted for 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.

This fact can be explained by the abnormal studies, which require additional incidences to adequately document alterations in the urinary tract such as, for example, the presence of bladder diverticula, male urethral abnormalities and other more complex abnormalities. Post Your ideas for Miccionaal.

After the bladder filling phase, the voiding study is performed with anteroposterior radiographs in the case of girls, and with lateral or oblique, in the case of boys.


Dose and image quality in the comparison of analogue and digital techniques in paediatric urology examinations. Login or register free and only takes a few minutes to participate in this question.

Thus, if radioprotection of patients exposed to ionizing radiations is important, it is moreover so, with pediatric patients 1,2.

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 mjccional some technical non-conformity might be happening, and thus justify the high doses observed in cistourrtrografia present study.

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.

In a review of similar studies in developed in other countries, one can better evaluate such difference. Radiation dose measurement and custouretrografia estimation for paediatric patients undergoing micturating cysto-urethrography. Close and don’t show again Close. 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.

Term search All of ProZ. Automatic update in However the values found were discrepant, ranging from 0. Evaluation of work practices and radiation dose during adult micturating cystourethrography examinations performed using a digital imaging system.
