Quantitative analysis of contrast-enhanced ultrasonography (CEUS) images based on time-intensity curve fittings in a child without kidney disease (a & b) and in a pediatric patient with CKD stage 5 (c & d). Three regions of interest (ROIs) were placed in the cortices, and three ROIs were placed in the medullas. Quantitative parameters of wash-in blood flow, including A, B, k, and TtoPk, were generated automatically for each ROI
