Hints
• CARE Bolus may be used to optimize the bolus tim-
ing.
• Set the ROI for monitoring scan in the abdominal 
aorta with triggering threshold of 120 HU, or use 
manual triggering.
• Do not administer oral contrast medium, as this 
impairs the editing of MIP/SSD/VRT images.
• Use water as oral contrast.
• The length of the CM spiral in the topogram (via the 
table position) can be planned exactly by means of 
pre-contrast images.
• Precontrast images are used to visualize calcifica-
tion.
• Excellent post-processed images can be created 
using a thin slice thickness and overlapping images, 
i.e. the increment should be smaller than the slice 
thickness.
