Kidney diseases in children are relatively frequently requiring a constant imaging investigation for detecting progression disease in order to avoid or to delay renal failure.
Pediatric patients are more sensitive than adults to X-ray because this exposure can cause DNA damages and can increase the cancer risk per unit dose.
For these reasons, the reduction dose in children is imperative.
We currently use CT urography (CTU) exams for pediatric patients with distinct protocols respecting ALARA principles (as low as reasonably achievable). However, the individual risk from X-ray imaging is small when compared to the benefits consisting in an accurate diagnosis.
Split-bolus CT (SBCT) technique is the first imaging tool used for dose reduction. In complex cases, we use an adapted protocol consisting in two-phases CECT (corticomedullary and nephro-excretory phase) comparing to adults in which we use three phases CECT.
