Pediatric urologic advanced imaging: techniques and applications.

Diagnostic imaging of pediatric urologic disorders is continuously changing as technological advances are made. Although the backbone of pediatric urologic imaging has been ultrasound (US), voiding cystourethrography (VCUG), and radionuclide scintigraphy, newer and advanced modalities are increasingly becoming important. The aim of this review is to discuss the techniques and clinical applications of 3 such imaging modalities as they pertain to pediatric urologic disorders: MR urography, advanced US (harmonic imaging, 3D, voiding urosonography), and CT angiography.
