Tracheal and 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 trachea and continues through the left and right main bronchi. There are 110 slices scanned at 3 mm apart with a 1.5mm overlap.

Surface render

The airway:

The trachea and the bronchi are segmented out of the scan.
