CT Small-Artery Loss Tracks Severe Pulmonary Hypertension in COPD and Fibrosing ILD More Closely Than Parenchymal Damage

CT-derived pulmonary vascular metrics, especially the small-artery to total arterial volume ratio, identify severe pulmonary hypertension in chronic lung disease, with distinct vascular remodeling patterns in COPD and fibrosing ILD.
