Abstract

© Springer Science+Business Media New York 2014. All rights are reserved. The unique nature of nuclear imaging allows for detailed functional information lacking in other conventional imaging modalities, such as estimation of global and differential renal function, highly sensitive imaging of the renal cortex to document renal scars, evaluation of urinary drainage to aid in the diagnosis of obstruction, surveillance monitoring of vesicoureteral reflux, and evaluation of testis perfusion in cases of suspected testis torsion with equivocal ultrasound imaging. The authors outline a brief history of nuclear imaging in pediatric urology and briefly discuss general information including commonly used radioisotopes and comparative radiation dosage. Frequently ordered imaging tests are DTPA estimation of GFR, DMSA renal cortical imaging, MAG3 diuretic renal scan, nuclear cystography, and scrotal scintigraphy. Clinical indications, suggested techniques, sample protocols, diagnostic utility and accuracy, as well as controversies in interpretation are discussed for each study. Additional comparisons between nuclear and conventional imaging with regard to sensitivity, specificity, and radiation dosimetry are provided.
