Objective: We determined the reliability of a three-dimensional (3D) ultrasound (US) segmentation software for evaluating volumetric hydronephrosis index (HI) and renal parenchymal and pelvicalyceal volume in children with urinary tract dilation (UTD).

Material And Methods: From 1/2019 to 9/2023, children clinically scheduled for a renal imaging exam to assess UTD at a single center were prospectively enrolled. They underwent a dedicated two-dimensional (2D) and 3D US renal exam.

Article Synopsis
  • The study focuses on the biomechanics and deformation patterns of abdominal aortic aneurysms (AAAs), highlighting that some AAAs can rupture despite being small and that size alone isn't a reliable risk indicator.
  • Researchers recorded ultrasound video clips from 50 AAA patients, analyzing the vessel wall's strain patterns and discovering that these patterns are more reproducible than traditional size-based assessments.
  • Findings suggest that using strain patterns could improve risk assessment for AAA patients, but the clinical reproducibility of the specific strain measurements was found to be poor.

Background: The current management of abdominal aortic aneurysm (AAA) hinges upon assessing diameter using ultrasound (US). Diameter reproducibility with conventional two-dimensional ultrasound (2D-US) is challenging and requires experienced operators. A novel automatic three-dimensional ultrasound (3D-US) system enables on-cart software-assisted diameter estimation (3D-SAUS), potentially facilitating more precise diameter measurements than 2D-US.

Purpose: Ultrasound imaging is key in the management of patients with an abdominal aortic aneurysm (AAA). It was recently shown that the cyclic diameter variations between diastole and systole, which can be quantified with US imaging, increase significantly with the strength of the applied probe pressure on the patient's abdomen. The goal of this study is to investigate this effect more thoroughly.

Background: Three-dimensional ultrasound (3D-US) and computed tomography (CT) have proven abdominal aortic aneurysm (AAA) volume a more sensitive measure of growth than diameter. This proof-of-concept study aimed to investigate the clinical applicability of two-dimensional ultrasound and 3D-US for AAA diameter and volume growth pattern evaluation.

Methods: AAA patients with at least three follow-ups within a minimum of 24 months were included prospectively and consecutively from the COpenhagen Aneurysms CoHort (COACH).
