Examples of a moderate liver and a moderate lung IF in different field of views. a An example of a moderate liver IF (a hypervascular lesion) in a full field of view (FOV) with a ‘soft tissue’ window level (C:40 W:400). b The same CTA as a, but in a small FOV, in which the moderate liver IF falls beyond the area of this reconstruction. c An example of a moderate lung IF (a lung nodule) in a full FOV with a ‘lung’ window level (C:-600 W:1200). d The same CTA as c, but in the small FOV, in which the lung nodule falls beyond the area if this reconstruction
