Ultrasound appearance of the neonatal kidney
Normal sonographic appearance of the neonatal kidney
In normal term neonates, cortical echogenicity is equal to the hepatic or splenic parenchymal echogenicity, presumably due to the increased volume of glomeruli and greater amount of cellular components in the renal cortices as compared to adults. The normal neonatal kidney also demonstrates a well-delineated corticomedullary junction with prominent and hypoechoic medullary pyramids.
