Example of an atypical segmentation error in a patient pulmonary artery (left). Portions of nearby vessels (e.g., ascending aorta) were captured. However, the centerline skeletonization around the PA junction was not affected by the segmentation leakage and correctly computed the maximum distension in the trunk and pulmonary main (right). PT indicates the pulmonary trunk, while RPM and LPM the right and left pulmonary main.
