Patient
male, 2 month(s)
 
 
  • Figure 1
    Plain radiograph of the child

    Plain chest radiograph of the infant shows evidence of gross cardiomegaly.

     
    Area of Interest: Cardiovascular system; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 2
    CTA images displaying criss-cross pulmonary arteries
     

    CTA axial image shows the origin of left pulmonary artery from the main pulmonary artery to the right and superior to the right pulmonary artery. AO: aorta; PA: Main pulmonary artery; LPA:left pulmonary artery

     
    Area of Interest: Cardiac; Imaging Technique: CT-Angiography; Procedure: Education; Special Focus: Congenital;

    The subsequent inferior section of axial CT shows the origin of right pulmonary artery. AO: aorta; PA: Main pulmonary artery; RPA:right pulmonary artery

     
    Area of Interest: Cardiac; Imaging Technique: CT-Angiography; Procedure: Education; Special Focus: Congenital;
     
     
  • Figure 3
    Volume rendered image

    Volume rendered image shows the criss-cross pattern of branch pulmonary arteries. RPA: right pulmonary artery; LPA: left pulmonary artery; PA:main pulmonary artery

     
    Area of Interest: Cardiac; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Special Focus: Congenital;
     
     
  • Figure 4
    MPR image displaying Left Ventricular wall ischemia

    Multiplanar reconstructed coronal image shows gross dilatation of left ventricle with presence of subendocardial ischemic hypodensity (arrow). LV:Left ventricle

     
    Area of Interest: Cardiac; Imaging Technique: CT-Angiography; Procedure: Education; Special Focus: Congenital;
     
     
  • Figure 5
    CTA and VRT image showing ALCAPA
     

    Axial CT image shows the anomalous origin of left main coronary artery from the pulmonary artery from right lateral aspect. LM:left main; PA: main pulmonary artery; AO: aorta; LAD: left anterior descending coronary...

     
    Area of Interest: Cardiac; Imaging Technique: CT-Angiography; Procedure: Education; Special Focus: Congenital;

    Volume rendered image shows that left main coronary artery is arising from main pulmonary artery and dividing normally into left anterior descending and left circumflex artery. LM: left main coronary; LCX: left...
