Hints
CARE Bolus may be used to optimize bolus timing.
Set the ROI for monitoring scan in the aorta abdom-
inalis 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 postprocessed images can be created using
a thin slice thickness and overlapping images, i.e.
the increment should be smaller than the slice thick-
ness.
Contrast medium IV injection
Start delay 10 – 15 sec.
Flow rate 3.0 – 3.5 ml/sec.
Total amount 100 – 120 ml
