I was told by a GE applications person that I should use a LARGE field of view, which was big enough to include the shoulders.
She said this was because with a small field of view the density standardising peripheral detectors (64 slice) would not be scanning air if a small field of view was used.
This was illogical to me - I was after spatial resolution for 3D reconstructions, rather than measuring densities.
What is the correct method? - for CT angios and for CT neck?
