Imaging techniques in paediatric renal disease

In many ways the imaging of paediatric renal disease is not dissimilar to that in adults. After all, a kidney is a kidney. But in many ways it’s different too. While the core modalities of ultrasound, fluoroscopy, MR, CT and nuclear medicine are used across the age spectrum from the cradle to the grave, the way those modalities are used and the range of pathologies varies immensely. CT and MR have become the main tool for imaging adult kidneys; this is partly due to the exquisite images that these modalities produce and partly because ultrasound is becoming less useful in our increasingly girth-challenged adult population. Moreover, in adults many investigations will be either for trauma or to exclude malignancy, both of which need definitive imaging at the first examination, often in the acute setting.
