We have encountered some CT series where a scout is referenced via the Referenced Image Sequence in the axial slices, however the Frame Of Reference differs between the scout and axial slices.
Am I correct in the assumption that we may not display slice lines on these supposed scouts, since the Frame of Reference UID is different? The coordinates seem to match however. Or is there a special rule that allows usage as a scout in any case if it is referenced via Referenced Image Sequence?
