Dynamic Contrast-Enhanced Magnetic Resonance Imaging for the Evaluation of Hydronephrosis in Children

[摘要] Hydronephrosis is detected on 1 in 800 to 1500 prenatal sonograms. Most mild grades of dilation resolve spontaneously. Because there is no test that absolutely defines obstruction, moderate-to-severe grades of hydronephrosis pose a diagnostic dilemma for both pediatric urologists and pediatric radiologists. To date, most pediatric urologists employ a combination of sonography, radionuclide scintigraphy, and voiding cystourethrography to elucidate the cause and severity of the hydronephrosis.
