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).
Figure 2. Two hepatic metastases. (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 smaller metastasis, lying just posterior to the middle hepatic vein (arrow), is much more clearly seen on the thin section (a), although it is still visible on the summated thicker section (b).
Figure 3. A subtle metastasis in segment 7 of the right lobe of the liver (arrow). (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 metastasis is not seen on the summated thicker section (b).
