Pediatric urologic imaging.

Significant advances have been made in the imaging of the urinary tract in children. The trio of renal-bladder ultrasound, voiding cystourethrogram (VCUG), and nuclear scintigraphy dominate this imaging. CT and MRI, however, are rising in utility to supplement these studies and in some cases provide the definitive imaging. This article provides the radiographic findings associated with the most common pediatric urologic problems and some less common anomalies. The focus will be on ultrasound, VCUG,and nuclear studies with CT and MRI discussed as pertinent.
