Background/introduction
The voiding cystourethrography (VCUG) is a medical-radiological procedure used in suspected vesicoureteral reflux (VUR) or bladder / ureter abnormalities [1,2].
The procedure consists of a dynamic evaluation under fluoroscopic control with acquisition of X-ray images (Fig.1).
The examination is subject to large variations of the total fluoroscopy time and the number of images.
This variability is linked to factors attributable both to the patient (clinical history,
conformation,
level of cooperation) and to the operator's experience,
and inevitably affects the dose to the organs.
A valuable tool for the optimization of radiological procedures are the Reference Diagnostic Levels (LDR) available for several years.
Limited to a few X-ray diagnostic methods,
especially in the pediatric field,
such as CUM,
the data available are still few.
Only in 2015 the European Diagnostic Reference Levels for Pediatric Imaging,
published the European guidelines on LDR for Pediatric Imaging (PiDRL) [3] (Table 1).
