Figure 1. Hazy peritoneal fat density surrounding the pancreas (arrowed in (a)) in a case of resolving acute pancreatitis. (a) 2.5 mm axial slices displayed as acquired directly from the multislice CT scanner. (b) 1.0 cm axial slices produced by summating four 2.5 mm axial slice acquisitions, as sent to PACS. The pathology is more clearly seen on the thin section (a), although it is still diagnostic on the summated thicker section (b).
