研究目的:

本研究旨在运用常规超声、超微血流成像、超分辨超声造影、超声粘弹性成像多模态超声成像及人工智能探索和分析儿童股骨头微循环血流及关节软骨弹性特征,建立一种客观定量、实时动态的儿童髋关节术后股骨头微循环灌注评估体系,揭示术后股骨头血流动力学变化规律,探讨术后微循环变化与临床预后之间的关系,为临床早期发现AVN,早期干预及预后评估提供客观影像学依据。  

Objectives of Study:

This study aims to utilize multimodal ultrasound imaging techniques like conventional ultrasound, Superb Microvascular Imaging(SMI),Super-resolution contrast-enhanced ultrasound (SR-CEUS) , ultrasound viscoelastic imaging, integrated with artificial intelligence, to investigate the microcirculatory blood flow within the femoral head and the elastic properties of articular cartilage in children. The primary goal is to establish an objective, quantitative, and real-time dynamic assessment system for evaluating microcirculatory perfusion in the pediatric femoral head following hip surgery. This system is intended to elucidate postoperative hemodynamic changes within the femoral head, investigate the relationship between postoperative microcirculatory alterations and clinical outcomes, and provide objective imaging evidence for the early detection of avascular necrosis (AVN), timely intervention, and prognosis assessment in clinical practice.
