CV6 Diameter of the right descending pulmonary artery/probability of shunt [radiography]

  • Holger Pettersson

When a left-to-right shunt is suspected, evaluation of the width of the pulmonary vessels is important. On the AP radiographs the right descending pulmonary artery may be measured with accuracy. In the present assessment, the width of the right descending pulmonary artery has been compared with the trachea, to eliminate variable factors such as magnification, age and body surface area.
