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.
