Quantitative ultrasound renal parenchymal area correlates with renal volume and identifies reflux nephropathy.

Purpose: Studies show that renal volume on magnetic resonance imaging correlates with differential function and is decreased in children with vesicoureteral reflux diagnosed after urinary tract infection. We examined the correlation between ultrasound renal parenchymal area and magnetic resonance imaging volume to determine whether quantitative ultrasound renal parenchymal area might be a reliable, less costly and less invasive substitute for renal magnetic resonance imaging volume.

Materials And Methods: To determine the correlation of ultrasound renal parenchymal area with magnetic resonance imaging, we identified 82 children with primary vesicoureteral reflux who underwent renal magnetic resonance imaging and ultrasound.
