3D Technique Used |
Thresholding on Advantage windows 3D |
|
|
Comment: If you increase the pitch to 2 you can scan the entire airway. This is more logical. IV contrast may be helpful in staging tumors by defining nodal disease. The authors reconstructed the raw data with the bone algorithm. We do not use thresholding for 3D studies but recommend volume rendering as well as MIP. |
