Bronchial Stenosis

by Janice Cook-Granroth in consultation with Dr. McLennan

Patient History for Tracheal Stenosis

MPEG Movies of the Tracheal Stenosis

Original CT scan

Movie:

This scan starts at the neck and continues through the tracheal stenosis. There are 406 slices scanned at 1 mm apart with a 0.5mm overlap taken on the helical CT scanner. Slices 320-323 and slices 324-327 show the obstruction in the lingular divison bronchus.

Surface render

The airway:

The trachea through the some of the bronchus is segmented out of the scan.
