The aim of this study was to evaluate renal parenchymal thickness and renal cortical thickness measurements on brightness mode ultrasound (B-mode US) and B-mode US + Superb Microvascular Imaging (SMI) technique, comparing with computed tomography (CT) or magnetic resonance imaging (MRI) serving as a reference standard.
Renal parenchymal thickness and renal cortical thickness measurements were obtained from B-mode US, B-mode US + SMI, and CT/MRI in a group of healthy subjects and a group of patients with chronic kidney disease (CKD). The mean differences and correlations of renal parenchymal thickness and renal cortical thickness were analyzed using dependent pair t-test and Pearson's correlation, respectively.
The mean difference in renal cortical thickness measurements between B-mode US + SMI and CT/MRI was lower than the mean difference between B-mode US alone and CT/MRI. Additionally, renal cortical thickness measured using B-mode US + SMI showed a stronger correlation with values obtained from CT/MRI than values measured using standard B-mode US alone.
The measurement of renal cortical thickness by B-mode US + SMI is more accurate than that by B-mode US alone.
本研究旨在评估在亮度模式超声（B 型超声）和 B 型超声+超微血流成像（SMI）技术上测量肾实质厚度和肾皮质厚度，并与计算机断层扫描（CT）或磁共振成像（MRI）作为参考标准进行比较。
在一组健康受试者和一组慢性肾脏病（CKD）患者中，从 B 型超声、B 型超声+SMI 和 CT/MRI 中获取肾实质厚度和肾皮质厚度的测量值。使用配对 t 检验和 Pearson 相关分析分别分析肾实质厚度和肾皮质厚度的平均差异和相关性。
B 型超声+SMI 与 CT/MRI 之间的肾皮质厚度测量的平均差异低于 B 型超声与 CT/MRI 之间的平均差异。此外，与仅使用标准 B 型超声测量的值相比，B 型超声+SMI 测量的肾皮质厚度与 CT/MRI 获得的值相关性更强。
B 型超声+SMI 测量肾皮质厚度比仅使用 B 型超声测量更准确。
