Comment: An initial spiral scan of the entire chest was done before the focal spiral protocols listed above. This protocol is done without intravenous contrast material. We prefer to use IV contrast in these cases and find that the quality of the 3D image is better. We also will routinely use thin section CT (2.3) as our initial study.
