研究目的:

本研究旨在开发并验证一套全新的、无创的宫腔粘连(Intrauterine Adhesions, IUA)全周期管理体系。该体系通过深度整合剪切波弹性成像(Shear Wave Elastography, SWE)技术以实现病变的定量诊断与分级,并结合人工智能(Artificial Intelligence, AI)进行智能化分析与预后预测。研究的核心目标是显著提升IUA的诊断准确性,优化宫腔镜粘连松解术(Transcervical Hysteroscopic Resection of Adhesions,TCRA)的手术精准度,有效降低术后再粘连率,并最终改善IUA患者的生殖预后。  

Objectives of Study:

The present study aims to develop and validate a novel, non-invasive full-cycle management system for intrauterine adhesions (IUA). This system enables quantitative diagnosis and grading of lesions by deeply integrating Shear Wave Elastography (SWE) technology, and conducts intelligent analysis and prognosis prediction in combination with Artificial Intelligence (AI). The core objectives of the study are to significantly improve the diagnostic accuracy of IUA, enhance the surgical precision of transcervical hysteroscopic resection of adhesions (TCRA), effectively reduce the postoperative re-adhesion rate, and ultimately improve the reproductive prognosis of patients with IUA.
