(A) Adjustment of the axis and plan appropriate to the tracheobronchial tree in multiplane reconstruction CT images; measurements of diameter and area of the trachea at (I) subcricoid (II) aortic arch level and (III) proximal carinal level in coronal (B) and axial (C) plans are demonstrated. (B) carinal angle (green lines), (D) Anteroposterior diameter (yellow arrows), transverse diameter (orange arrows), (E) area measurement (blue circle) at the relevant level in the trachea are shown
