Abstract

Purpose

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.

Methods

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.

Results

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.

Conclusion

The measurement of renal cortical thickness by B-mode US + SMI is more accurate than that by B-mode US alone.

超级微血管成像在慢性肾脏病肾皮质厚度测量中的附加值。

目的：本研究旨在评估亮度模式超声（B-mode US）和B-mode US + 超微血管成像（SMI）技术的肾实质厚度和肾皮质厚度测量结果，并与作为参考标准的计算机断层扫描（CT）或磁共振成像（MRI）进行比较：方法：通过 B 型 US、B 型 US + SMI 和 CT/MRI 测量一组健康受试者和一组慢性肾脏病（CKD）患者的肾实质厚度和肾皮质厚度。结果显示，肾实质厚度和肾皮质厚度的平均差异和相关性分别采用因果配对 t 检验和皮尔逊相关分析：结果：B型超声+SMI与CT/MRI的肾皮质厚度测量值的平均差异低于单独B型超声与CT/MRI的平均差异。此外，与单独使用标准 B 型 US 测量值相比，使用 B 型 US + SMI 测量的肾皮质厚度与 CT/MRI 测量值的相关性更强：结论：使用 B 型 US + SMI 测量肾皮质厚度比单独使用 B 型 US 测量更准确。

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
