研究目的:

本研究旨在通过对功能性动态数字X线摄影(DDR)技术在慢性血栓栓塞性肺动脉高压(CTEPH)诊断中的应用进行前瞻性研究,确立基于DDR技术诊断CTEPH的最佳信号强度阈值(cutoff值),建立科学、可靠的肺血流灌注定量分析方法,为CTEPH的临床诊断提供一种新的无创性评估工具。  

Objectives of Study:

This study aims to conduct a prospective investigation on the application of Dynamic Digital Radiography (DDR) in the diagnosis of Chronic Thromboembolic Pulmonary Hypertension (CTEPH), establish the optimal signal intensity threshold (cutoff value) for CTEPH diagnosis based on DDR technology, develop a scientific and reliable quantitative analysis method for pulmonary perfusion, and provide a new non-invasive assessment tool for clinical diagnosis of CTEPH.

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

现行的诊断流程通常涵盖初步评估、血流动力学评估和影像学检查等环节。初步评估包括对患者临床症状的详细询问、体格检查和超声心动图等非侵入性检查,以初步识别可能的 PH 患者。在血流动力学评估中,右心导管检查作为确诊 PH 的金标准,用于测定肺动脉压力和血流动力学参数。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

The current diagnostic algorithm typically includes an initial assessment, hemodynamic assessment, and imaging tests. The initial evaluation includes a detailed examination of the patient's clinical symptoms, a physical examination, and non-invasive tests such as echocardiography to initially identify a possible patient with PH. In hemodynamic evaluation, right heart catheterization serves as the gold standard for confirming the diagnosis of PH and is used to determine pulmonary artery pressure and hemodynamic parameters.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

基于 DDR 确立 CTEPH 诊断的最优肺血流信号 cutoff 值,建立肺血流灌注定量分析方法。
