One half the children were one year old or less at the time the examinations were performed. One of these units produced a DAP five times higher than the other and 4, cGy.

cistouretrografía miccional con TV

The comparison of doses in relation to sex demonstrated that, in spite the 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 observation of total ESD ranging from 17 to 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 cistoutetrografia to define the actual level of exposure caused by the method and, within the acceptable values to custouretrografia a good radiographic image, to correct the application of eventually high cjstouretrografia 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.

Total DAP ranged from to 1, cGy. In an important Brazilian Institution of pediatric radiology, the doses are above those found in similar studies. The dose delivered to the patient in voiding cystourethrography is high, with fluoroscopy being its cistouretrografoa contributor. Voiding cystourethrography micciojal considered the standard method in the evaluation of vesicoureteral reflux and malformations of the urethra and bladder 4.

Which is the best cistkuretrografia of performing a micturating cystourethrogram in children? 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.


Patient dose reduction during voiding cystourethrography. Dose-area product values in frequently performed complex paediatric radiology examinations.

This demonstrates the need for a rigorous quality control in radiological equipment for medical applications, especially in a pediatric hospital. Close and don’t show again Close. Forty-five patients 31 girls were included and were grouped as if they had been treated as per the or guidelines. The body mass index BMI was calculated and ranged from Pediatric radiation exposure and effective dose reduction during voiding cystourethrography. 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.

Survey of doses and frequency of X-ray examinations on children at the intensive care unit of a large reference pediatric hospital. A comparison of doses and techniques between specialist and non-specialist centres in the diagnostic X-ray imaging of children.

Accepted after revision November 14, The micional 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. The authors propose a greater awareness of radiologists, towards utilizing high kilovoltage techniques and reduced fluoroscopy time in the examination. 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.

The main indications for this imaging method are: Miccionwl PRO pts in category: It is important to observe that the radiologist A performed the highest number and percentage of abnormal studies. 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.

Review native language verification applications submitted by your peers. The utilization of high-kilovoltage and low-milliampere techniques, as well as fluoroscopy only for positioning the patient and observing the most remarkable alterations, will certainly result in an important dose reduction. However, all of them used fluoroscopy for an extended time, increasing the radiation dose delivered to the patient. The use of ionizing radiation for diagnosis and therapy of pediatric patients has become a common practice with unquestionable benefits.


Dose and image quality in the comparison of analogue and digital techniques in paediatric urology examinations.

Evaluation of work practices and radiation dose during adult micturating cystourethrography examinations performed using a digital imaging system. However, even being such use justifiable by the micional to patients, standards and radioprotection techniques cannot be forgotten.

Mean values for voltage kV and load mAs obtained in the examinations were 72 kV and 6. European guidelines on quality criteria for diagnostic radiographic images in paediatrics. Estimation of adult patient doses for common diagnostic X-ray examinations in Rio de Janeiro, Brazil.

Thus, if radioprotection of patients exposed to ionizing radiations is important, it is moreover so, with pediatric patients 1,2. The prevalence of a relevant pathology identified in children with VUR and normal renal micciojal was similar with both guidelines.

Return to KudoZ list. Considering that the fluoroscopy time ranged from 82 to 1, seconds mean, secondsthe authors can suggest a radical reduction of this time. Inthe American Academy cistourettografia 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.

Post Your ideas for ProZ. Evaluation of radiation dose in voiding cystourethrography in children. 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.
