title: Tomography of the pulmonary hili. Anatomical reassessment of the conventional 55 degrees posterior oblique.
abstract: Classic anatomical drawings of the pulmonary hili based on conventional 55 degrees posterior oblique tomograms must be modified to include the superior pulmonary veins, which can be more prominent in oblique projections than in anteroposterior views. Inadequate understanding of the limitations of conventional tomography in soft-tissue analysis, combined with simplistic modeling of hilar anatomy in fixed oblique orientations such as 55 degrees, can lead to errors in diagnosis.
