A useful projection for demonstrating the bifurcation of the pulmonary artery.
The demonstration of the pulmonary bifurcation is important in order to exclude pulmonary branch stenoses. The origin of the right and left pulmonary arteries can be demonstrated in the anteroposterior plane if cranial angulation is used. Depending on the course of the left pulmonary artery, the origin of the left pulmonary artery may not be seen in spite of the maximal cranial angulation. On the lateral plane without tube angulation the origin left pulmonary artery is commonly superimposed on the origin of the right pulmonary artery. If maximum caudal angulation is added to the steep left anterior oblique view, not only the left, but also the origin of the right pulmonary artery can be seen.
