Files in this Data Supplement:

• Video 1 - Full forced expiration manoeuvre in a healthy volunteer. 2D rf-spoiled gradient echo sequence (SPGR) with Temporally Resolved Imaging of Contrast Kinetics (TRICKS). Sagittal view of complete expiratory maneuver in mid-trachea position, 48 volumes collected in 19 seconds. Note that the tube like configuration of the trachea remains intact.
• Video 2 - 3D Surface Rendering of the lung and central airways during a breath-hold in full inspiration (Patient F).
• Video 3 - 3D Surface Rendering of the lung and central airways during a breath-hold in full expiration (Patient F).
• Video 4 - Forced expiration manoeuvre of patient F. 2D rf-spoiled gradient echo sequence (SPGR) with Temporally Resolved Imaging of Contrast Kinetics (TRICKS). Sagittal view of complete expiratory maneuver in mid-tracheal position, 48 volumes collected in 19 seconds. Note the dynamic narrowing of the middle section of the trachea.
• Video 5 - Full forced expiration maneuver in patient F. 3D Surface Rendering of the complete forced expiratory manoeuvre, 48 volumes collected in 19 seconds. Note the dynamic narrowing of the middle section of the trachea.
