Which view best assesses the spatial relationship of the great arteries and the trachea?

The ability to judge how the great arteries relate to the trachea relies on a view that includes both the mediastinal vessels and the trachea in the same plane. The three-vessel-trachea view does exactly that: you see the main pulmonary artery, the ascending aorta, and the superior vena cava in one slice, with the trachea in the midline behind them. This arrangement lets you directly assess whether the great vessels cradle or encircle the trachea, which is key for detecting vascular rings or abnormal arch configurations. Other views focus on different structures: the four-chamber view shows atrial and ventricular relationships, while the LVOT and RVOT views visualize the outflow tracts from the ventricles but don’t depict the trachea or the full vessel–trachea spatial relationship. Hence, the three-vessel-trachea view is the best choice for this assessment.
