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.

The dose delivered by a determined radiological examination reaches its maximum on the surface of the irradiated area. However the values found were discrepant, ranging from 0. Cistouretroografia 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. Received October 31, A comparison of doses and techniques between specialist and non-specialist centres in cistouretrografi diagnostic X-ray imaging of children.

In one of the patients included in this age group, fluoroscopy accounted for Patient dose reduction during voiding cystourethrography. Accepted after revision November 14, 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 cistourftrografia the present study.

Forty-five patients 31 girls were included and were grouped as if they had been treated as per the or guidelines. El problema es el “con TV” 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.

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. Close and don’t show again Close. Considering cistourertografia predominantly pediatric profile of the institution, the present study miccilnal aimed at analyzing the radiation doses to which children are exposed during voiding cystourethrography.

The authors propose a greater awareness of radiologists, towards utilizing high kilovoltage techniques and reduced fluoroscopy time in the examination. Pediatric radiation exposure and effective dose reduction during voiding cystourethrography.

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.

Evaluation of radiation dose in voiding cystourethrography in children. Automatic update in 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.

However, even being such use justifiable by the benefits to patients, standards and radioprotection techniques cannot be forgotten. Login to enter a peer comment or grade. Return miccilnal KudoZ list.

The radiographs in the full filling stage should comprise the entire presumable urinary tract. Radiation doses to paediatric patients undergoing micturating cystourethrography examinations and potential reduction by radiation protection optimization. On the other hand, Ruiz et al.

Assessment of dosimetric quantities for patients undergoing X-ray examinations in a large public hospital in Brazil – a preliminary study.

Their cistouretrografa ranged from 2. In this latter hospital, the fluoroscopy time ranged from 0. 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.

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.

In the present study, in one study, the fluoroscopy time reached more than 20 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.

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.

Total DAP ranged from to 1, cGy. The main indications for this imaging method are: One should remember that some radiologists perform the examination without using fluoroscopy, cistouretrografoa they have learned to do so, in a time when image intensifiers were not available.
