Steady state free precession images of the pulmonary arteries. The main pulmonary artery can be seen in the oblique sagittal image (panel a). The pale band shows the location of the cine acquisition that transects it (panel b, arrow). The right and left pulmonary arteries can be seen in the scout image (panel c). The bands indicate the locations of cine acquisitions transecting the right (panel d, arrow) and the left pulmonary artery (panel e, arrow)
