Fig. 2From: Feasibility of contrast-enhanced ultrasonography (CEUS) in evaluating renal microvascular perfusion in pediatric patientsStatistical analyses of contrast-enhanced ultrasonography (CEUS)-derived quantitative parameters (A, B, k, and TtoPk) between the renal cortex and medulla as well as the left and right kidneys. Regions of interest (ROIs) 1–3 are located in the renal cortex, and ROIs 4–6 are located in the renal medulla. These results showed robust reproducibility of CEUS quantitative parameters in analyzing microvascular perfusion in pediatric kidneysBack to article page
