Hints

You could repeat the same protocol by simply click- ing the chronicle with the right mouse button for “repeat“, e.g., when both non-contrast and contrast studies are required.

For lung cancer evaluation, this protocol can be com- bined with the protocol “Neck Routine”.

Low dose lung images are usually evaluated using lung window setting. Soft tissue/bone window set- tings may be used to visualize the presence of calci- fications in the nodules.

It is essential to use the same protocol for follow-up studies to check for progression.
