Tracheal and Bronchial Megaly

by Janice Cook-Granroth and Dr. Wcisel




Patient History

The patient has tracheal and bronchial megaly along with bronchiectasis (ballooning) of the airways with a small amount of emphysema.



MPEG Movies

The original Imatron CT scan.

The original trans axial section 28 slice Helical CT data set of a patient. The volumetric data acquisition of 10 mm thickness the trachea, and the lungs.

Surface Display of airway.

This movie is of the airway from the larynx to the main bronchus. This movie rotates about the y axis in ten degree increments.
