*Axial = A medium-sized axial pulmonary artery gives rise to a branching, smaller-sized artery.
†Dichotomous = A normal-appearing vessel bifurcates into two equally sized branches.
N = Normal pulmonary artery.
C = Concentric-obliterative lesion.
P = Plexiform lesion.
D = Dilatation lesion.
? = Vessel disappears in distal sections.
