研究设计:

Study design:

Sequential 

研究目的:

1.主要目的:以肺动脉造影作为金标准,明确DECT(dual-energy CT one-stop imaging)肺灌注的诊断效能,有利于直接指导治疗。 2.次要目的:DECT取得的灌注缺陷评分结合功能学指标灌注血容量百分比(PBV)与反映CTEPD患者的临床状态的数据之间的相关关系,为CTEPD患者特有的危险分层提供依据。  

Objectives of Study:

1. Main objective: To use pulmonary angiography as the gold standard to clarify the diagnostic efficacy of DECT (dual-energy CT one-stop imaging) pulmonary perfusion, which is conducive to direct guidance of treatment. 2. Secondary objective: The correlation between the perfusion deficit score obtained by DECT combined with the functional index perfused blood volume (PBV) and the data reflecting the clinical status of patients with CTEPD provides a basis for the risk stratification unique to patients with CTEPD.
