Comment:
- Evaluation of the airways can be done with or without IV contrast,
depending on the clinical suspicion. 3D and MPR imaging can better
define the pathology in many cases.
- High resolution algorithm is used in these cases.
- Varying the rendering parameters creates beautiful virtual images.
