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. |
