Figure 8 Axial sections of CT pulmonary angiography in a 2-month-old female with infective endocarditis. A: Complete occlusion of the left pulmonary artery by a thrombus on blended contrast image; B: Complete occlusion of the left pulmonary artery by a thrombus on low kV (80 kV) image, showing increased contrast in the vasculature; C: Lung vessel image showed blue color-coded right pulmonary artery (white arrow) with thrombus being color-coded red in the left pulmonary artery (black arrow), suggesting diminished iodine content; D: Lung blood volume image showed diffusely reduced perfusion in the left lung as compared with the right lung.
