Figure 4 (A-D): Pulmonary artery abnormalities. Axial CT scan (A) shows a large intraluminal filling defect in the left pulmonary artery (arrow) consistent with acute pulmonary embolus. Coronal reformatted CT image (B) shows a linear web in the right interlobar artery, consistent with chronic pulmonary embolus. Axial CT image (C) in a patient with history of recurrent pulmonary embolism shows severely dilated pulmonary arteries, consistent with pulmonary arterial hypertension. Axial CT image (D) in a patient with acute pulmonary embolism and pulmonary hypertension shows dilatation of the right ventricle and bowing of the inter-ventricular septum to the left side, consistent with RV strain
