This study presents a systematic application of a unified vascular obstruction scoring system across dual-energy CT, cone-beam CT, and digital subtraction angiography in patients with chronic thromboembolic pulmonary hypertension. The results demonstrate significant correlations with invasive hemodynamic parameters, with dual-energy CT and cone-beam CT providing higher reproducibility than angiography. These findings support the use of a standardized scoring framework to enable consistent multimodality assessment, improve reproducibility in structured multimodality imaging assessment, and facilitate cross-institutional comparisons in chronic thromboembolic pulmonary hypertension.
