New imaging applications in the evaluation of pediatric renal disease

Continued improvements in imaging technology have changed many of the traditional diagnostic algorithms for evaluating pediatric renal disease. Newer imaging modalities offer more accurate, specific, and early diagnoses, but can be time consuming and costly. Less invasive modalities, such as ultrasound, computed tomography, and magnetic resonance imaging have widespread applications in pediatric practice. The risks of radiation exposure, contrast toxicity, and sedation or anesthesia versus the potential benefits of obtaining precise diagnostic information should always be considerations before electing any imaging procedure in children.
