  • Figure 1
    Axial CT pulmonary angiography
     

    CT pulmonary angiography, axial MIP image revealed dilatation of the pulmonary trunk and right main pulmonary artery. Note absence of arterial flow to the left lung

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    CT pulmonary angiography, axial MIP image revealed oligemic left lung which is supplied with dilated intercostal arteries (yellow arrow).

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Special Focus: Congenital;
     
     
  • Figure 2
    Axial MIP and 3D images of the pulmonary vasculature
     

    CT pulmonary angiography, axial MIP image revealed oligemic left lung with absent left pulmonary arterial supply. This is associated with increased right pulmonary vasculature.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    3D- MIP of the pulmonary vasculature revealed oligemic left lung with increased right sided pulmonary vasculature.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Special Focus: Congenital;

    3D volume rendering image for the pulmonary arterial tree showing absent left main pulmonary artery.
