Abnormalities of Pulmonary Vasculature in Pulmonary Hypertension.; (A) White blood anatomy showing right upper pulmonary vein stenosis at the site of a prior ablation for atrial fibrillation (arrow). (B) Congestion and infarction in the right upper lobe on Half-Fourier Acquisition Single-Shot Turbo Spin-Echo images in the same patient (asterisk). (C) Magnetic Resonance Angiography from a separate patient with PH due to fibrosing mediastinitis; a varix is seen bypassing a stenosed left upper pulmonary vein (not shown) alongside stenoses of both right sided pulmonary veins (arrows). (D) Magnetic Resonance Angiography in patient with Chronic Thromboembolic Pulmonary Hypertension. The most striking feature is loss of the left descending pulmonary artery (arrow head).
