by Janice Cook-Granroth in consultation with Dr. McLennan




Patient History for Tracheal Stenosis

The patient is a 55 year old male with cancer. He also had an hlo esophageal performed.



MPEG Movies of the Tracheal Stenosis

Original CT scan

Jan. 7, 1998:
This scan starts in the chest area just below the neck and continues through the left and right main bronchi. There are 112 slices scanned at 3 mm apart with a 1.5mm overlap.

July 7, 1999:
This scan starts near the mouth and continues to the left and right main bronchi. There are 168 slices scanned at 3 mm apart with a 1.5mm overlap.

Surface render

Jan. 7, 1998
